I have been working for the last couple of years on my fictional East Texas Branch of the Texas & Pacific Railroad.  The era is early 1940s.  All steam.  Located in East Texas it branches off west from the T&P mainline somewhere between Atlanta, Tx and Jefferson, Texas.   All trains run from Texarkana, Tx yard and Terminate at the end of the branch at Casey.  There are two towns, Casey and Mckenzi Junction, both named after my daughters.  There is a 3 track yard and multiple industries in Casey.  Casey is the west end of the branch.
