Couldn't a six-compartment tank car make as many as six deliveries
to customers? I forget the name for this type of tarriff but I think that
cars could make multiple stops to drop partial cargos. So if there were
a small bottler in Gridley who buys wine in 1,000 gallon lots (enough
for 1,000 large jugs of wine), then that might work... If you think about
it, a small town of 1,000 people on average consumes somewhere
around that amount of wine every year.
