By the numbers
I've got a scenario that starts out with about 100 cars. 50 or of these cars have to be shunted around to various areas in during the scenario. The problem is that i've got duplicate car numbers, some of the numbers duplicated more than once. Seems easy enough to change the unique numbers using RW Tools then re-selecting those cars in the Scenario editor. Question is though is what causes the number duplication problem and how do I prevent it in the future?
