Piston Revised

Basic Piston Rig from Tracy Blankenship on Vimeo.

Part 1) Illustrating the basic connections of the rig
Part 2) Illustrating the default acceleration/deceleration of the user-input train speed
Part 3) Illustrating how the optional train engine weight affects the rate of acceleration
