I would DEFINITELY buy type 7s or 8s in HO scale. I have a Boeing LRV in MBTA livery in HO scale (made by Mehano for IHC). 2 of the trucks pick up power and the third one drives. It runs at a prototypical speed (slow like it should be) although the motor doesn't seem to like the weight of the unit overall.
Anyone know if I can remotor it? I know that Custom Traxx has a new floor with dual motors and a Bowser mechanism, but it's $95. I paid $55 for my Boeing and I don't want to spend that much on a new floor.
The pictures of the models for the subway cars look great! Can't wait to see a casting of the 0700s!
About the PCCs, Bowser makes them undecorated and they are basically a hunk of lead. They need to be painted although the bowser mechanism runs great. They're also fairly inexpensive. If you don't care too much about detail, Bachmann BLUE BOX (not the old white box) PCCs doesn't have an interior, but runs very good and could be repainted for MBTA. They recently came out and I saw one running and was impressed with how smooth and quiet it was (for a bachmann)
If you want to wait, Custom Traxx is also doing painted Bowser PCCs for MUNI. One of the cars on the list is BERy #1059. (currently running on MUNI with a BERy paint scheme) When they come out, it will cost $109.95 according to their web site:
