Jim,
A control point or controlled signal is a home signal controlled by
the dispatcher. An intermediate signal is an automatic block signal and
not controlled by the dispatcher. A distant signal is one that tells the
crew that the next signal is a controlled signal. For example,
Cloverdale branch is black, Track Warrant territory and has no signals
for its entire nine mile length, other than an Approach Distant signal
before the signal governing movement off of the branch back out onto the
mainline. It never changes, so, does not provide any block protection.
