Using this method, the train lengths would only be limited by the upper arm
strength of the person pulling it - so prototypical 100+ car trains (1)
could be moved around at realistic scale speeds. That would be an
impressive sight to behold, all those double stack intermodal cars, boxcars,
tank cars, etc. going down the tracks as the person pulls them along.

Actually, the magnetic couplers would be the limiting factor before the
strength of the person pulling the train became an issue. I’m sure someone
here knows what the critical number of cars is before the lead coupler can no
longer bear the load. I’m guessing it’s around 20 or so. (and fewer if the
cars are 8-wide). Of course, some builders have overcome this problem by
using rare-earth magnets between their couplers, which are stronger.

During the last show that the Sydney LEGO Train Club displayed at, using an RC
locomotive with two power bogies, we were able to pull about 27 carriages before
the magnet couplers unbinding from each other. The magenets we used were the
‘regular’ LEGO magnet couplers, and not the rare-earth magnets that Jordan
mentioned.
