Both actually. I use the remote for manual control during
demonstrations. For unattended operation during train shows,
however, I just run a small NQC program that keeps things moving.
That would include the turntable motor, trolley motor, and
hook motor. A micromotor for the small utility crane above
the counterweight is controlled only by hand, unfortunately.

Done. Look beside the pic of the RCX. It's not much more than
a sequence of commands with random delays. Wouldn't be hard
to further randomize the exisiting sequence by adding
conditionals that evaluate the random function call. Another
way would be to build up a complex set of sequences that could
be selected at random.
