Today at the TTOS SP meet, Jeff Meyer and myself pooled all our Dorfan for a display, two loops running. The loop on the right was all Dorfan track, switches, transformer, lock on etc. The left loop was on L 027, but a Dorfan transformer. Note the desk lamp used to power the screw in cord.
Everything displayed is operable, except the green loco displayed split open. It will also be running soon, but with a Williams power truck.
