Press the green flag and you should hear the locomotive start up. Left arrow make you move backwards at a slow/fast rate. Right arrow makes you go forwards at a slow/fast rate. Space key is brake, it sets the locomotive speed speed to 0. H and J control the long and short Nathen Hybrid K5LLA horn. B controls the bell (I am not sure what it is called) Thanks to Jean Dennis-Bachand for the drawings.
