How about: on each bogie but the first/last, have 2 vertical axles, one
for each car; each with a 24t gear (the 2 of which are meshing).
Mount the 2 cars using that bogie (or their pendulum bases, rather) on
these 2 axles, and the bogie will always be at the midpoint of their
relative angle. That's still not perfectly in line with the track
at all times, but closer than being locked to one car.
