D to accelerate, A to decelerate, Space Bar to maintain speed. Stop at a station to refill on coal, and drop off and pick up passengers. Don't miss the stations! The blue light flashes when you are approaching a station. To choose a new paint job, push left/right arrows when the paint job screen is up.
