Early Temiscouata Track Standards (Tentative)

After looking at many pictures and trying to determine various dimensions from known components here are a few rough observations that will probably need to be refined when more information will be available. One thing is sure, the trackwork was so full of discrepancies many jigs available on the market just fail to convey that look. I'll probably have make a few of mine.

Rails:

-60 lbs
-28 feet long (to be confirmed by standard 1890s practices, TMC built the line with 32 feet flat cars)
-4-bolt joint bars

Ties:

-Height: 7 inches
-Width: highly variable, from 8 to 10 inches
-Length: average 8 feet 6 inches(it varies wildly in fact)
-Spacing: 24" center/center


Turnouts:

-Type: stub switch
-Switch machine: wooden with large target

3-way stub switch in Ste. Anne de Beaupré. TMC had longer central post (O. Lavallée)

Ballast:

-Mainly dirt with some bigger chunk
-Doesn't reach the top of the ties (about 3 to 4 inches of clearance under the rail)

Telegraph Poles:

-Single pole, no crossarm, single insulator on wood corbel

  1. I love that you have embraced these issues!

    1. 1:64 is an invitation to not overlook these isn't it?

  2. I use Code 70 rail on my Port Rowan in 1:64 layout and it nicely represents a 60-pound(ish) prototype rail. As you've noted elsewhere on this blog, the small rail and S scale track gauge really emphasize the light construction of prototypes such as yours (and mine). The nice thing is, Code 70 is big enough to provide reliable surface contact for the electrical path from track, to wheels, to motor, and it's big enough that it won't kink easily when you're spiking it. I had both those problems on my last HO scale branch line layout, where I used Code 55...
    Cheers!

    1. You are right. It's interesting to be able to use reliable HO scale components in a larger scale where they can be perfectly to scale.
