- Switch numbers
- Rail size
For the latter, I took some pictures of the side of the rail as show below:
The pictures -- admittedly grainy cell phone ones in low light -- have rail markings of "ASCE 9040" on them.
However, now I was left with a quandary...What exactly does "ASCE 9040" mean? My first rough guess was that it probably meant that it was 90lbs/yd rail, but I wasn't sure about the "40" part.
Fortunately, I follow Chris Mears' Prince Street blog, and in a recent posting, he was musing about an idea to catalog the various types of track as a reference for model railroaders. In the same vein as Railpictures.net, I'd say that's a great idea. Prototype photos are the best resource and realistic track weathering is one of my top priorities as well. Chris' idea generated some comments on his blog, one of which was a link to a rail-markings database of sorts.
Sure enough, "ASCE 9040" is in that table and reprinted here for completeness and archive purposes:
|90||5 3/8||5 3/8||2 5/8||ASCE 9040 1940|
Coupling that data with another reference site serving all of the major scales, and I've now learned that I need approximately code 117 rail to accurately depict the Fairgrounds Branch in miniature.
So, in short, while I was only able to manage a short trip, I was able to check off two particular prototype details and heavily influence design and early construction.
