Does anyone know or know where I can find out the track numbering scheme used by Great Northern. I can find schemes for many fallen flags, but not GN.
Do you mean how GN numbered freight yard tracks or ??
Specifically freight yards, but many lines have schemes that cover the entire range.
I don’t know that GN had a set standard of numbering tracks. Even if they did, it could change over time as a yard was expanded (or contracted).
The Great Northern Railway Historical Society republishes many prototype documents, including track charts. I have used these a couple of times for client projects, but I don’t recall a consistent numbering scheme from location to location. There are numbers on each yard track in some of the diagrams, but they are car capacities.
If you are not already a member, well worth the investment.

The problem is that rail yards, with a few exceptions, tended to grow organically over time. GN’s east-west mainline puts in a long passing siding in the middle of nowhere. In time, traffic warrants putting a yard there, so six yard tracks are put in north of the main, numbered 1-6 (south to north). Later, six more tracks are added south of the main, and numbered 7-12 north-south. A while later, track 2 is removed to make room for some reason (like adding diesel fuel storage tanks) so the tracks go 1-3-4-5-6 now.
Thanks. It is the way many roads number. Geographical depending on overall direction of mainline. Then numbered from there as you describe. Others and Santa Fe is a good example have a fairly detailed numbering scheme. Thanks again.
Thanks. I am building a layout inspired by the SF&N branch line and I have copies of their timetables from the historical society and they too identify yards by capacity. Most lines seem to work on direction of mainline I.e. North-South then number the yard tracks East or West out from the mainline. Many yards go on historical local names that the yard workers use. So far AT&SF had one of the most detailed system schemes.
