I've posted this code from Microsoft Train Simulator's version of the Gresley A1 "Flying Scotman" to compare it to the same locomotive simulated (albeit as an A3) in Auran Trainz. Note the logical, standard units used. I would argue that this is far better format for entering engineering data, as anyone, engineer or not, can understand it and transfer specs directly to the simulator.
