Well the one I found, I asked the seller a question.. came across as being rude.. so I passed on it. But I did get a pair of the 70' cars for 100.00. Made a test run. Only had to open a few tunnels between rooms. As you can see only one lights up.. I'll have to fix the other. If they were any longer, I'd have to adjust track for clearance in few spots.
On my road trip, train shop had some heavy lionel sp cars that were 2" longer than mth...
More overhang than I thought on 54.. can't believe these will run on a smaller radius...
I was guessing the engine, and tender together was 29"... I was trying to see what the engine, and tender lengths apart were... or if in fact the engine is 29" by itself.
