In the constant combinators in the top row, - Set [item=locomotive] to the train limit. (1 by default--trains won't queue up.) - Set [virtual-signal=signal-C] to the number of cars in the train. (4 by default.) - Set [virtual-signal=signal-S] to the item stack size. (50 by default.) 3. Name station. 4. PROFIT!
