Wild West railroad truss bridge - MOC

[Murdoch17]

This 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.

A big thank you to Wes Turngate over on Flickr for helping get the angle right to put the bridge supports in place. The LDD file is slightly different than the pictures as it is 2/3 of a brick taller to add in the proper parts to make it work.

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).

The old design is on the left, new is on the right. (NOTE: The new bridge is in the LDD file, but the old one is NOT!)

Here is the ldd file for the newer bridge: bridge link As usual, comment, questions and complaints are always welcome!

Ah, yes. I remember seeing that bridge before. And looking at the bulky lower side I think it will hold. 

But your version is nice as well. You might have a look whether you can tile it a bit. And maybe you can make the sides three wide? I think it would make it look less massive.

It’s a great design but the sides just look a little too massive for a wooden bridge of that era. I also question how well the tracks will be held in place with a train running.

I agree with @gotoAndLego that the beams for the bridge are too thick; the should probably be 2 studs or less imho. Other than that, this looks like a decent bridge to best be placed low, over a small river or shallow crevasse.
