Detailed video of yard operations on the HO scale KCS 3rd sub. Nearly all trains into and out of the yard are shown. Somewhat long: we condensed a 3 1/2 hour operating session down to 67 minutes.
Begins with a 1 minute 40 second narrated overview - skip that if you want to get right to seeing the trains running.
The RFID system is shown in this video. To learn more about that, see this video: https://youtu.be/v2rSqCuwZlU
Note: This was recorded during the COVID-19 Pandemic. You'll see some people wearing masks, but many others not. All people not wearing masks have been fully vaccinated for a minimum of 20 days.
