elevations

[DSchmitt]

There is no hard and fast rule, but generally small numbers next to the track are used to indicate the elevation of the track above the base elevation of the layout. The base elevation "0" is usually the elevation of the lowest point on the track. Scenic features may be below the base elevation. The elevation may be the top of rail, top of base board or top of roadbed. As long a it is consistent, it really should not matter which, although it is prudent to check clearances before finalizing the the vertical placement of the track where one track crosses over another. The needed clearence may vary depending on the thickness of materials used (base, roadbed, tie thickness, and rail code), and type of bridge (if used).

Can you give us some more info such as who the plans are by? Are the numbers in anyway related to any other aspect of the plan? By this I mean is the number beside any feature or landmark or is it by itself?

Is there any documentation beside the actual plan? It should say there, those I've seen so far are all about the rise, but who knows... We would need more info to give you a good reply.

I'm not sure if the numbers on the track plans indicate for instance 3 equals a 3 inch rise and a 1 equals a 1 inch rise. Please let me know if I'm right.
Thanks,
