All three operational loops that we had at Supertrain were dogbones, and
worked well for crowd-pleasing. The only real hitch was that we couldn't
run many long trains becuase they'd keep dropping cars or slowing/stopping
on the end loops because of friction around the loop. The longest train we
could consistently run was about 12-15 cars of 6-wide passenger stuff
(mostly JamesP & Zonker's VIA trains), and even that would occasionally lose
the last few cars going around the end of the dogbone.
