Not to hijack the thread, but did Lionel ever make an RS-3 with a pullmor?
No. the first Lionel Rs3's came in the mid 1990's with a stamped metal frame- correct fuel tank and can motors in the trucks- a la K-line/RMT types. Late 1990's or in the new century Lionel "cheapened" the RS3 with a plastic frame and hand rails, incorrect GP fuel tank, and one vertical can motor with NO flywheel.
