How to Learn "Railroad Speak"?

[dave1905]

Since you are modeling the BNSF, that means you are in the modern era, so it will be track warrants instead of train orders.

Track warrants are point to point authorities issued verbally (over the radio) from the dispatcher to the train crews. The train crews fill out a standard form with the information and authority the dispatcher gives them.

Dispatcher:
Track warrant no 1245 to BNSF 5725 at Pearland.
Check box 2 proceed from Pearland to West yard limits Dixie yard on main track.
Check box 7 this is not in effect until the arrival of BNSF 9022 at Pearland.

Train Crew:
Track warrant no 1245 to BNSF 5725 at Pearland.
Check box 2 proceed from Pearland to West yard limits Dixie yard on main track.
Check box 7 this is not in effect until the arrival of BNSF 9022 at Pearland.
Two boxes checked 2 and 7

Dispatcher:
That is correct

Train Crew:

If you search for "track warrants" or "GCOR" (General Code of Operating Rules) you can find out more information.

Since your railroad probably isn't signalled, only one train can occupy a given set of limits (unless its a joint authority)
