Lately I have been playing around with LEGO (again). To pretend that I am an adult I’m designing models with Lego Digital Designer. It took some getting used to, but it is a nice tool. Also it runs perfectly in Wine (on my Mac running Linux).

I’m toying with a plan to build a LEGO train triangular Warren truss bridge.

Not having build it, I can’t really say if a train passes under it (think it does), and if it is structurally sound (again I think so).

Here is a side view.

The only annoying bit is that I could not line up the top the beam, I think if I were to build this I could make that work, but I’m slightly worried it has some real life repercussions.

The lxf file can be found here.

Update⌗

Full (i.e. longer) bridge (still the annoyance of those top beams).
