    Why Roller Coaster Track is Filled with Sand

    January 17, 2020


    For the past century, theme parks all over
    the world have been battling one another to construct taller, faster, and more exhilarating
    thrill machines in order to outshine the competition and attract the largest crowds. Driving this battle forward are the engineers
    and roller coaster designers who have developed innovative ways to build these towering structures
    so that they are both safe and reliable. Over the years, each roller coaster design
    company has established their own signature design style with recognizable characteristics
    that set their coasters apart from the rest. A few examples include the I-beam design of
    Rocky Mountain Construction, or RMC, which consists of a continuous steel I-section with
    integrated rails; The truss design of Intamin, which consists
    of small steel tubes that are welded together to form a 3-dimensional truss;
    And the box beam design of Bolliger and Mabillard, or B&M, which consists of a continuous steel
    box section that supports two rails using fin plates. Although the various design styles are quite
    unique, they all accomplish the same task of supporting high-speed roller coaster trains
    as they hurtle through the air. If you have ever been to a major theme park,
    you may have noticed that in addition to having a unique visual appearance, each track design
    also produces a distinct sound as the trains speed over them. The sound produced by a given roller coaster
    is directly related to the design of the track, and of all the various track styles, the box
    beam design produces one of the loudest and most recognizable sounds. The box beam track design developed by B&M
    has a continuous steel spine that is formed by a hollow rectangular cross-section. Steel fin plates are welded to the top of
    the spine at regular intervals, and these fin plates support the two rails which are
    made from circular steel tubes. When trains travel along the rails at high
    speeds, vibrations are induced in the track which propagate throughout the entire cross-section. These vibrations generate sound that we can
    hear, and the large hollow box beams actually amplify the sound due to their size and geometry. Although the roar of a B&M roller coaster
    is iconic and downright intimidating, the noise can be a problem in certain situations,
    particularly when theme parks are located adjacent to residential areas. A prime example of this is Canada’s Wonderland,
    which is a theme park located in Ontario, Canada. The park first opened in the early 1980’s,
    and at that time it was surrounded only by farm land. However, that farm land was gradually overtaken
    by urban sprawl as the nearby city expanded, and a large residential area was eventually
    constructed adjacent to the park. Now perhaps you shouldn’t move into a house
    located across the street from a theme park if you don’t like the sound of roller coasters,
    but a lot people may have overlooked this issue at the time. In 2006, Canada’s Wonderland was purchased
    by the Cedar Fair Entertainment Company, which invested millions of dollars into the park
    to build numerous world-class thrill rides. The biggest of them all came 2012, when Canada’s
    Wonderland introduced Leviathan; The tallest roller coaster that B&M had ever built to
    date, standing at 93 m tall and reaching speeds of nearly 150 km/hr. The giga coaster was constructed right at
    the front of the park, and it extended out into the parking lot just a few hundred meters
    away from the neighboring residential area. And was this coaster ever loud. Every time a train dived down the first drop,
    the sound could clearly be heard by the residents across the street, and this obviously led
    to numerous noise complaints. The park hired an acoustical consultant to
    perform an assessment of the sound produced by the ride, and it was determined that something
    had to be done to quiet down the Leviathan. In the end, it was decided that the best way
    to reduce the noise produced by the roller coaster would be to fill the track with sand. Since the first drop was the primary culprit
    of the noise problem, attention was focused only on this part of the ride. It was not possible to fill the rails with
    sand because this would require the rails to be cut open and welded closed, which would
    be detrimental to the smoothness of the ride, however they could cut open and fill the box
    beams. Once engineers determined that the structure
    and its foundations could support the additional weight, the park moved forward with their
    plan. First, a hole was cut into each box beam section
    of the first drop by workers on a large boom lift. Sand was then blown into each section using
    an aggregate blower, which used compressed air to deliver the sand to the required height
    through a long tube. Since each section of track is sealed at both
    ends where the individual pieces are bolted together, sand had to be blown into each track
    section individually rather than filling the entire box beam at once. After the entire drop was filled, the holes
    in the box beams were welded shut and the work was complete. This method of noise reduction was successful,
    and the noise produced by the roller coaster was greatly reduced. The sand inside the track works by damping
    the vibration of the steel which reduces the amplitude of the resulting sound waves. As the steel walls of the box beam vibrate
    against the sand, the walls push against the sand and move the individual particles, which
    transfers energy away from the steel. This loss of energy translates to a reduction
    in the amplitude of the vibrations, and the volume of the sound is therefore reduced. The same technique has been used for a number
    of other roller coasters as well, including Gatekeeper at Cedar Point in Ohio, and Yukon
    Striker at Canada’s Wonderland. However, for these two coasters, it was known
    in advance that noise could be a potential problem, and so the rails were filled with
    sand during track fabrication before the roller coasters were erected. It’s likely that the engineers decided to
    fill the rails and not the box beams in these two cases because a smaller volume of sand
    is required, and it would have been very difficult to transport and install the track pieces
    if they were completely filled with sand due to the huge increase in weight. Even though less sand is used, filling the
    rails alone is still an effective method for reducing the level of sound produced by a
    roller coaster. Filling roller coaster track with sand has
    been shown to be a good solution to the noisy roller coaster problem, and it can be used
    for both new roller coasters as well as existing roller coasters. It is a clever yet simple technique, and perhaps
    we will see it implemented more frequently in the future. Hey everyone, thank you for watching this

    San Diego Track Work Projects: Train Talk Ep. 20

    November 23, 2019


    Hello everyone and welcome to Train Talk! In this episode, we are going to take a look
    at several track improvement projects that are happening in San Diego County, California
    along the coastal rail line known as the LOSSAN corridor. We’ll visit several different sites and
    take a look at some of the work being done at each location. But first, let’s take a look at some background
    information. The rail line between San Diego and Los Angeles,
    California is the second busiest passenger rail corridor in the United States. This line was completed in 1887 and for many
    years, it consisted of mostly one track with occasional sidings where trains traveling
    in opposite directions could pass each other. In the 1990’s, the rail line was purchased
    by local transit agencies from the Santa Fe Railroad. Various improvements were made, upgrading
    the tracks and rebuilding several sidings that were removed by the Santa Fe. Today, as may as 24 Amtrak, 26 Coaster, 46
    Metrolink, and 5 freight trains a day travel along at least a portion of the corridor between
    San Diego and Fullerton. With additional train traffic expected in
    the future, there is a need now more than ever to expand train capacity and upgrade
    various sections of track. In this video, we will be focusing on the
    portion of the line within San Diego County, a total of about 62 miles. This stretch of railroad is owned by the North
    County Transit District, which is the transit agency that operates the Coaster commuter
    trains between Oceanside and San Diego. There are several different construction projects
    underway that we will be taking a look at in this video. SANDAG, or the San Diego Association of Governments,
    is the regional transit planning agency for the greater San Diego area and they are the
    main agency responsible for managing all of these projects. Over the next 20 years, nearly one billion
    dollars of investment is planned for the rail corridor in conjunction with a multi-billion
    dollar investment in added bike trails and Interstate 5 improvements in the northern
    coastal portion of San Diego County. As of 2018, about 66% of the rail corridor
    in San Diego County is double tracked. The long term goal is to have 99% of the route
    double tracked in San Diego County by the year 2050. In addition to adding more sections of double
    track, other projects include station improvements, grade separations, and bridge replacements. We will start in San Diego and work our way
    north toward Oceanside. The first major construction project north
    of San Diego is the new railroad bridge over Friar’s Road. This bridge is located just north of the Old
    Town Transit Center and is the first section of single track to the north of downtown San
    Diego. This short single track section creates a
    choke point where trains have to wait for each other to cross the bridge one at a time. The old single track bridge is being replaced
    with a new, steel girder double track bridge over Friars Road and the San Diego River,
    connecting a section of double track located to the north with the one to the south. This will result in the complete elimination
    of single track railroad in this area. Half of the new bridge is already open to
    train traffic with the second track opening some time in 2019. The new bridge is shifted slightly to the
    west of the old bridge in order to accommodate a new extension of the San Diego Trolley. This new trolley line will extend the blue
    line from Old Town north along the current railroad right of way to UCSD and University
    Town Center. The new route will feature a combination of
    at grade track along with several sections of elevated rail line along Interstate 5 and
    Genesee Avenue. This extension is expected to open in 2021. A few miles north of the Friars Road Bridge
    is the next major construction site in Rose Canyon. This is one of the largest construction projects
    currently underway and will result in a second track being added between Balboa Avenue and
    the highway 52 overpass. In addition to a second track being added,
    several bridges are being replaced and some curvy segments are being straightened to increase
    speeds through the canyon. Certain sections of track are also being raised
    to protect them from periodic flooding. In some areas, the tracks need to be shifted
    over to make room for the trolley line, which will be running along the rail line through
    much of the canyon. This project is expected to be completed in
    2020 Currently, there are no track work projects
    in Sorrento Valley but just a few years ago, a second track was added both north and south
    of the station and two bridges were replaced. The bridge to the north of the station was
    replaced with a new concrete span. The tracks were also raised, like many sections
    in Rose Canyon, to protect them from periodic flooding. South of Sorrento Valley, there is still one
    more section of single track railroad over Miramar Hill. This section will be double tracked and straightened
    to increase speed limits some time in the future. The Torrey Pines Bridge Replacement is another
    project that was recently completed but is also worth mentioning. 5 aging wooden bridges through the Torrey
    Pines State Reserve were replaced with new concrete bridges. This section was not double tracked because
    it is possible that this area will eventually be bypassed with a two track tunnel underneath
    Del Mar. Another major track improvement project is
    in full swing in between Solana Beach and Cardiff. The San Elijo double track project is one
    of the two largest construction projects currently underway along the coastal rail corridor. This project involves adding a second track
    between the current sidings at Solana Beach and Cardiff, replacing a very old wooden trestle
    over the San Elijo Lagoon, and improving the railroad crossing at Chesterfield Drive with
    more barriers, warning signs, and landscaping. The improvements at the Chesterfield Drive
    crossing will allow for a quiet zone to be established in the future. As of June, 2018, the new concrete bridge
    has been completed and track installation over the bridge is also in progress. A “universal crossover” is also being
    added just north of the Chesterfield crossing. A universal crossover allows trains to switch
    over between either track in both directions. The estimated completion for this entire project
    is late 2019. Just north of Encinitas in La Costa, a new
    track project is expected to begin in late 2018. This is another bridge replacement and double
    track project that will eventually see the old wooden bridge over the Batiquitos Lagoon
    replaced with a new double track concrete bridge. Construction on this project has been delayed
    but in 2016, the estimated completion date was some time in 2019. In Carlsbad, the Poinsettia Station is receiving
    a number of safety enhancements. The current platforms will be replaced with
    longer, slightly elevated ones that will make boarding much easier. The at grade pedestrian crossings are also
    being replaced with a pedestrian underpass, similar to the ones that can be found at Old
    Town and Oceanside and a fence will be placed between the two tracks. This will allow a train to pass through the
    station at full speed while another train is loading on the other track. Currently, approaching trains are required
    to stop outside of the station if there is another train loading. This project is expected to be completed by
    2020. The final project that I’ll mention for
    this episode is the Oceanside Quiet Zone Construction. As of mid 2018, not much work has been done
    on this project but by some time in 2019, all 5 railroad crossings along the coastal
    rail corridor in Oceanside are expected to become quiet zones. This means that engineers will no longer be
    required to sound the horn when approaching railroad crossings, although they are still
    allowed to if the need should arise. Improvements to the crossings will include
    new signage, raised medians in the road, and additional fencing and traffic signals. Thank you for coming along for this look at
    several railroad construction projects along the coastal rail corridor in the greater San
    Diego area. For a full listing of past, current, and future

    Planet Coaster | Society Park Part 29 | Farm Station

    November 14, 2019


    Hello fellow Planet Coaster Lovers! Welcome back to Society Park and welcome into a new area. The healthcare area is finished except from the transition plaza to this new area. However I wanted to start in this new area first so I could see how the two themes to transition from. And what better way to start of the area by building the monorail station. It actually won’t be finished till the next episode but the it illustrates a good image of where I’m going to The music also kind of gives it away xD This song is actually loopable so I could let you guys listen to it for a whole 21 minutes. But I think you guys would go crazy so I didn’t loop it.You’re welcome. This area is about agriculture so hence why I start of by building a typical farm in here. In this area you’ll also find the more rigidy rides, funfair quality mostly. Also it will be more for kinds since I’m planning to place a ferris wheel in here and some more calm rides. Offcourse this area will also get a wooden roller coaster and I’ll try to make it CGI worthy. So when riding that one you should probably leave you’re 4 year old child in the ferris wheel ;P Anyway the station will be a bit simple since I don’t have much room and it is a monorail station. The length of those stations definetly give me trouble in making it look not that boxy. However the guests are only able to see the front facade so I think I could manage in making it look interesting. By the end of this episode only the entrance side of the station will be a bit more finished. Might still tweek it here and there but I’m pretty happy with how that turned out in the end. The back of the station will mostly be covered up by vegetation cause I don’t want people to be able to see the other area from the queue. In hindsight I might have placed these two areas a bit to close. But I did like the idea to see the ride flying over the station from time to time and it gives another challenge so why not? To illustrate you guys an image of how far the park is, we have finished the Economy and Healthcare areas. We still need to do this area (obviously) and then a Technology area. After that it should be around done So we’re about halfway there…. episode 29… Let that sink in for a bit because I sure have xD On the bright side, allot more content to look forward too. My pc has alread reached record heat and I’m able to start cooking from it in just a couple episodes. Running the park smoothly in lowest settings and 9 fps.. I was thinking for a moment to actually make this park into a scenario in the end but I think that actually be able to run this spark smoothly will be a challenge itself xD But I’m already in the scenario editor with this park since I wanted to improve the parking space so I might still change my mind. Still a long way to go so time enough to think that through. By the way have you seen my surprise of last Saturday? You know the first episode of a new project called Water Witch? If not, be sure to check it out. Anyway here I tried to make some big farm doors where a tractor or something could be behind. Thought of a second to maybe make open doors and a small farm interior. But then my pc froze so I quickly decided on not to do that to give my pc a little break xD But don’t worry to much yet, as long as it stays above 5 fps I will be able to build. Misplace some things here and there but that will just be the way it is. You might actually see that happen in some places of the footage. So that song is finally over, gone crazy yet? Imagine that for a whole 21 minutes xD I chose a more calmer song for now to let you guys calm down a bit, still allot more of happy music coming up Anyway thank you for joining again and I’ll talk to you guys in the next episode! See ya!

    Planet Coaster | Society Park Part 47 | Space station

    October 20, 2019


    Hello fellow Planet Coaster Lovers and welcome to another episode of Society Park! Also welcome to the beginning of the final area Technology! For this area I’m aiming for a bit more scientific theme which is actually the second time that I’m trying something with that theme. The first try was Space Program which actually didn’t include much scenery and such. So this will be a kind of a trial for the space like theme for me. Hence why the episodes of this series will be a bit slower in building and you’ll see me trying different things since I’m actually looking for the right things to mix This time I started with the monorail station, just like last time. I wanted to include allot of glass in this station but it still has to be different from the main entrance building. Which (like some of you remember) also has a glass roof , but using the windows which you can’t actually see through. The station in the end still has some simularities but I kind of like how it turned out. The station stands on its own at the moment but I think, when more theming happens, that it’ll fit quite nicely So bear with me in the coming episodes of me trying things out and if you have any tips then please don’t hesitate. Enjoy the remainder of the episode and I’ll see you guys in the next episode!

    ✔ Minecraft: How to make a Railway Intersection

    August 20, 2019


    How to make a Railway Intersection This railway intersection is both compact and well functioning. :] It’ actually really simple, but I find it hard to get started the right way for some reason.. If one of the rails won’t turn in the right direction, power it with a redstone torch. You can add signs in the middle to avoid any confusion about where you’re going! Your intersection shoud look something like this: Let’s try this beauty! I’ve set up 4 locations with different colors! The minecart will automatically go back to the intersection after visiting locations Let’s go for red! By pressing the button and moving in the deriction I want, I can control the cart. Let’s go for purple! Let’s go for yellow! Simply check the sign if you’re unsure whether or not you’re in the righ position. Feel free to click Subscribe if you haven’t already! Thank you to Zangas for supporting this video! You can now get Merchandize For all ages and genders, all around the world!
