n scale warren truss bridge

well, I thought I was making progress. I am installing a bridge that will span 12" so I purchased two Atlas N Scale Warren Truss Bridges. While working on the bridge abutment and pier height, I just realized that Atlas Code 55 track and the track on the bridge are different - I think the bridge track is code 80, but no where on the box, or Atlas website or Walther’s catalog can I find any specs on the track.

So … what is the trick to connect Code 55 track to the track on the bridge?

The real trick is to buy the code 55 track bridge.

Have you thought about using Central Valley’s N scale truss bridge? One bridge is about 12 inches long, and in my opinion, looks better than the Atlas warren truss bridge. Here is a link:

These bridges do not come with rail, you supply your own. I used ME code 55 rail for the bridge and mated it with my Peco code 55 track. A little soldering and a little filing was all it took to get a nice, seamless transition.

Aside from buying a different bridge, you might consider the following.

Attach the code 80 rail joiner as you normally would to the bridge track. “Squash” the extending portion of the rail joiner flat. You should find that the code 55 track will match the height of the code 80 when you solder it on top of the flat code 80 joiner.

You might need a “practice run” or three to get the amount of crush correct. I used this method to utilize a Kato double cross over with my code 55 track. The rail height match was good, and fortunately the Kato section is in an out of the way location and doesn’t look too out of place. Enough ballast will cover a multitude of faults.
