On the BNSF Ft.Worth sub, wheres their crew change points? North Yard,Witchata Falls, Alliance or Gainesville. I guess Temple is the west end change out.
I believe that that it depends on the type of train, etc. I think that all of the points you named are crew change points. Wichita Falls is actually on the BNSF Wichita Falls sub to Amarillo. I think that Quanah and Amarillo are also crew change points on the former FW&D, but don't quote me on that. There is a yahoo group dealing with Texas and surrounding states, Railspot, that would DEFINITELY answer your question. (which is a good one, BTW!!!) Go to http://groups.yahoo.com/group/railspot and you should get your answer.
