Bachmann has offered a point-to-point trolley set in On30 for several years. The most popular of these sets is in a Christmas motif, complementing the wide range of ceramic villages available from different mfrs. But, Bachmann has done this set in a more common, non-seasonal set decoration. And those trolleys are available separately, too.
If you want intermediate stops on this sort of a set-up, I highly recommend Dallee's trolley stop-and-go system using current-sensing for detection. For all the years we used this system (Our Christmas metropolis became overwhelming to recent demise as the body became less flexible!), it worked flawlessly.
