Press the Green Flag to start up the locomotive. When you press it, you should hear the locomotive enter a startup sequence. Left arrow makes the locomotive move left at a reasonably slow/fast rate. Right arrow makes the locomotive move right at a reasonably slow/fast rate. Space key is the brake, and it sets the speed of the locomotive to 0. H and J control the long and short 3 Chime. Bell is included, YET. RADIO CHATTER IS AUTOMATIC. C is for the chuffing sound.
