No - while it is on display, Protocraft is best. Happy to send a pair of Monarchs, if you decide on prototype-size Janneys, but the Protocraft are brass and easily polished. If you run it, just use a Kadee on oneend of the first car.
On the 4-40 screws - Micro Fasteners has really nice model hex head screws in brass. Wish they had steel. They look better than pan head slotted.
