This Update makes one change.

For switching (local service) trains, the classification routine that assigns cars to trains now checks for "room" (maximum train length based on the number of cars) taking into account where pickups are located.  "Pickups" which are at the same zone as the train are prioritized to be assigned.

If the car is at a yard at the same zone, it will be assigned (up to train-maximum-length in cars).

If the car is at a customer at the same zone, the car may be assigned - depending on the number of cars-in-train plus the number of (prior) pickups previously assigned at that zone.

I checked and tested this new 46 lines of code, and it works as expected.

OK?
