like mixing the train schedule and sequenced gearshaft together into a new block (should have train casing texture)
you can program it like a train schedule and when placed on a train it will give rotation to drive the train (trains move on rotation) according to the program.
have all the action of train schedule and add some more:
start driving forward/backward/left right
drive forward/backward/left/right [number] blocks
timed delay [number]
stop driving
start/stop steam whistle
ring bell
start/stop smokestack
open/close north/east/south/west/all door
wait for new redstone pulse
wait until reach station [name]
you can add more in comments
can copy command from train schedule
can only work on trains
