I recently came across a listing of NS Harrisburg Division Locals. Many of them are listed as "Turns" while the ones I'm familar with are not. What is a Turn?
The term might vary from place to place.
A turn here means your on the mainline board, but not on the extra board, "holding a turn".
Then a "turn around local" means you come back to the same terminal that you departed from. Those jobs here are assigned.
Another one is a "pool". The Cheyenne guys here get all the fast trains and run them most of the way across Wyoming, "long pool". Then theres the "short pool" guys that run the dogs from Cheyenne to Rawlins. From there the guys on the Rawlins "turns" bring the dogs to Green River.
Dont know what the real difference between them is.
