I'm still figuring out some operations on my layout and realized I created a little problem with my track plan! I'll try not to make this sound like a highschool algebra question )) but if there was a one way train traveling North from Kingsport to Sawyer (which is considered to be miles away) and cars there were ready to be picked up from both industry A and B that were to be shipped farther North.... 1. Would the Kings Port train crew curse my track plan for the switchback at Sawyer, uncouple from the train, run light to Sawyer, pick up cars at B, bring them back to Kings Port, run around the train and tack the cars on the end of the train, recouple, and then pick up cars at A 2. Pick up cars from both A and B and return to Kings Port with the engine in the middle of a run of cars and assemble the train at Kings Port 3. Or would some powers-that-be assign the job of picking up cars at B to another train, say a local turn that orignated from the North and returned there after working in Sawyer?
