Sell entire trains by selling the engine with Ctrl.
Configuration file: fastwagonsell
Command line: -Yw
It can be very annoying to have to sell each wagon individually when selling a train. With this switch, all you have to do is hold down Ctrl, sell the engine, and the entire train will be sold.
Alternatively, you can sell all wagons behind a certain wagon, by selling that wagon and holding down Ctrl as well.
