modern double track railroad truss bridge - 7900 inspired MOC - real world model
Murdoch17 posted a topic in LEGO Train Tech
This double track train trestle is finally finished! The bridge uses four girder parts from City set 7900 from 2006 that I've had laying around for 18 years without much luck at making a bridge (despite several attempts) - until now! The bridge is ~30 inches long, and is designed to hang between two tables with the parts under track off the end of the bridge proper serving as feet, holding the bridge level and on the table top. Looking up track through the centerline of the bridge. There are 16 bricks of space from top of the rail to the roof girders, which means it can take double-stack Maersk container cars with a plate to spare. To pick the bridge up, you can grab anywhere but the roof lattice - those plates aren't reinforced enough to take the weight. The underside has been reinforced since the initial design stage... It's a lot stronger now, and *should* be able to hang between two tables without breaking while trains run over it. (I've not been able to test this with motorized trains as I don't own any.) Thoughts, comments, questions? Feedback is appreciated! EDIT 7/6/24: Please pardon my messy layout! I've really got nowhere to go with most of this stuff, but nevertheless I just managed to rearrange it around, moving tables and adding my bridge to the mix. The bridge works beautifully and hasn't collapsed yet which I consider a major win for my design skills! A digital look at what the layout looks like without the stuff in the way. -
This through-truss bridge design was originally downloaded by me (I don't remember the name of the original designer who created the bridge) from the LEGO Factory / Design By ME page in 2010-ish and was never built in real life due to questions about it's strength. I came across it again while looking at my MOCpage account's older files and made it into the version seen above using newer parts and a longer frame quite a while ago. (and as to those original questions about it's strength: It's built like a safe, yet I can pick it up with a single finger by the top..... just don't drop it, because the reddish brown parts won't survive the landing!) More recently, I revised the deck where the track goes to be able to take the RC track up and be able to put down 9V down more easily. (We run 9V trains at shows in Gateway LUG.) In short, the track is now more easily removable to become 9V, 12V, or even a road bridge. The bridge fits any of my trains, and should fit all official LEGO trains except for double stack containers such as sets 10219 (Maersk Train) and 10170 (TTX Intermodal Double-Stack Car). Comments, questions, and complaints are always welcome! Many more Wild West items can be seen in my Historic sub-forum topic here.

Western-style wooden / iron truss bridge (nine tracks long- double tracked railroad trestle)
Murdoch17 posted a topic in LEGO Train Tech
One of the major problems of using my Eads bridge at shows is it's only one track wide.... so, I devised a western double-track wooden and iron structure using instructions from an old instruction I found on my hard-drive. (Originally from a defunct website / magazine called Railbricks and in a more modern concrete-looking format). This double structure is about 300 less parts than my single track Eads bridge and sits at the same height / length, so it can fit in the same spot. There are no bricks above track level at the beginning of the bridge so it works with even 10 wide trains or curves / switches immediately off the bridge! (This is unlike the Eads bridge, which cannot have turns right after it.) This trestle has about a track and a half of space between bridge end and truss section for an engine to straighten out on. The 10-wide BTTF time train fits easily though the bridge with room to spare! (time train not included in LDD file!) The new trestle is the same height and length as the Eads bridge, but with double the width for 300 less parts. The Eads bridge is also modular in construction, while the new one is not. (Eads bridge not included in LDD file!) LDD file for the wooden bridge (NO time train or Eads bridge in file!) is available at Brick-safe. Comments, Questions and complaints are always welcome! -
"The Crash at Crater Canyon (part 1)" is a thrilling two-part episode of the 1950s / 60s TV series Woody's Roundup. In this episode, Jessie the yodeling cow-girl is knocked out by Prospector Stinky Pete, as she had discovered Pete's plans for Sheriff Woody and the town he protects via the mine tunnels under the town filled with dynamite and nitroglycerin, set to blow up high noon the next day to destroy the town in a giant sinkhole. Jessie is then placed unconscious on a steam loco which is uncoupled from it's train and sent hurtling uncontrollably through the wilderness to Crater Canyon, where it will meet the Cannonball passenger train on the bridge. (Thus destroying the only fast way to town and keeping Jessie out of the way for the town to explode with Woody saving Jessie and not in town to stop Pete's plan.) Naturally, Woody rides out on his horse (Bullseye) to save Jessie,who has at this point woken up and discovered the throttle lever missing and steam loco's brakes disconnected. This episode ends with this scene above: Jessie reaching for Bullseye and Woody while both trains are barreling towards each other and certain destruction, while the timer on the clock in town square ticks ever closer to noon. What happens in the next episode will never be known, as the show was pulled from the airways as the film office where the future episodes and unfinished scripts were kept burned to the ground, destroying all the un-aired episodes. It is assumed, though, that Woody rescues Jessie, stops the town from exploding, and jails Pete all before the credits roll. The real scene takes place on my Eads bridge with engines 2 and 3, plus the passenger train for the latter loco. The yellow steamer is not even finished: the side not shown is missing one wheel and moving piston and was carefully staged to hide this fact! The story behind the picture is 100% fake, as the Woody's Roundup only exists in Disney / Pixar "Toy Story" films. (specifically the second one) I tried using every to make the story sound believable for that era of TV it was set in, such at the middle 1950's to early 60s when Howdy Doody and Westerns in general were very popular. What do you guys think?

Modular railroad trestle (Lattice Girder + Truss hybrid bridge)
Murdoch17 posted a topic in LEGO Train Tech
I took two bridge designs (lattice girder and truss) and combined them. I know it isn't realistic, but the design is the best I could come up with. However, the truss part is removable via Technic pins, so it can become more viable for display at shows or home layout use. Here is the bridge with the top trusses on. The bridge with the top trusses removed. The 18 Technic holes could be used for decoration of some sort. The two ramps (which are included in the LDD file) use two-thirds of a brick every 16 studs over three track-lengths to make the gap from base-plate level to full bridge height. PLEASE NOTE: Their is a height restriction for the bridge with the top attached if you use the Maersk double-stack train cars or anything taller than set 10014 (My Own Train - Caboose). The bridge will simply not fit anything taller without modifications. (The train car is NOT included in the LDD file!) Here is my original inspiration for the bridge, courtesy of Flickr user Fireglo450: lattice girder bridge on Flickr The Lego Digital Designer file for my model is here: LDD file This bridge will be built in real life sometime around January 2017.
