Morning Switch is an automated operation. After caching is complete, clear the screen (Ctrl/Space), tap the Z key a couple times, then sit back and watch the switch engines work while some through trains come and go. Note: tracking is set on chase so feel free to use the up,down and direction keys to follow the engines. Also, turn on the sound. The scenario is 60 minutes real time so if you feel the need, press the P key to pause.
