Ryan,
My layout is freelance; an On30 prosperous1950's narrow gauge railroad based in the Eastern Virginia Tidewater area that runs to the mountains.
Most of my rolling stock is either San Juan Car Co. or Accucraft. I acquired about 40 pieces for almost nothing before I started the current layout. I have a dozen Bachmann hoppers and six cabeese.
I have 3 MMI On30 locos (acquired with the rolling stock deal) that I equipped with Tsunami but do not operate as they are horrible runners. I operate using 2 B'mann 2-8-0s, 2 B'mann 4-6-0s, and 2 BLI 2-8-0s.
Everything is equipped with Kadee 803/807 couplers at On3 height. I find them to be much more reliable than the San Juans.
