If there are one or more locomotives with or without cars on the layout, you can start them or stop them by clicking the Run or the Stop buttons in the Control Train window.
Control: Train Window
Adjust the speed by dragging the slider (right is faster). When the "Automatic train stop" checkbox is checked, then trains will stop automatically in order to avoid collisions.
Management System
The Management System window allows you to control individual trains and the positions of the switches on the layout. The controls in the "Train" tab manage each locomotive (run, stop, reverse and turn) and the camera setting. The controls in the "Switch" tab manage the switches (light is straight on, grey is turning).
