Mario, Pete and Pat - Thank you all for the information. The 18" K-Lines I was thinking of are the TT Gray Pacemaker Set with Interiors.
I have a question. I don't care if the baggage car is lighted. So I was wondering if I am willing to put up with some flicker, does removing one center pickup per "Lighted" car have much of an effect on "rolling resistance"? Would daisy-chaining the lighting between cars, and say using just 3 pickups for the whole consist have much of an effect?
Thanks!
