ROCK 2.0 Rules
Rule #1 – All trains entering or crossing the mainline must obtain permission from the Rock Island dispatcher.
Rule #2 - If your train requires to work on the mainline, you must contact the dispatcher to receive a work order via the rules of Time Table and Train Order.
Rule #2b – Upon receiving the work order, the crew must place flags and appropriate fusees in either direction to protect the train and crew.
Rule #3 – At no time may a locomotive enter or pass-through a building. Crews must use spacer cars when such a situation arises.
Rule #4 – At no time may a car loaded with explosives be spotted or pass-through any structure.
Rule #5 – A caboose will be required on all trains on all freight and local trains.
I've been thinking too. To add interest to the crew operating the #118 LaSalle Turn, passenger operations would be in affect. I have found that when operating this train, you often have to leave a portion of your train out on the mainline. This would limit the location and time you could store your train on the mainline.
