Rail cars will indeed provide an adequate current path to shunt the rail
circuit and trigger the signal system. That's the whole point.
and in case anyone is interested, the railroads had to come up with ways
to deal with exclusivity, priorities, and scheduling in decentralized
systems about 100 years before these problems became well-known in
software. (indeed, failure to observe a proper semaphore system leads to
crashes, in either field)

(WWI is one of those wars for which no one has any good excuses as to why
it was started. One of the stories is that after the order was given for
mobilization into belgium (because it was widely believed at the time that
the road to moscow went through paris), the kaiser was about to change his
mind, but was convinced that the logistics of deployment were so intricate
that there could be no "undo". Years later, after all the destruction,
the guy who'd been in charge of the railroads published a book full of
charts and graphs and timetables to explain how, in fact, the order could
have been relatively easily reversed, had cooler heads prevailed)
