There were about twelve of us, two dispatchers, three yardmaster, and the rest operating trains. I was given control of the North West Special headed by SP6320.
I managed to traverse the multi-room layout without causing too much havoc, although I did end up in a bit of a traffic jam at one point. I stopped in Modoc to exchange some cars headed for Kalisbell. Luckily, the yardmasters took good care of me.
The dispatchers took it easy on me as well, giving me the main line most of the way. In all, the session took about three hours. After working on my tiny switching puzzle layout, this was quite an eye opener. A switching puzzle on a much larger scale!
