Franklin on the Cumberland branch with train 52.Trains on
the branch are assigned smaller motive power than those on

Adding a relay is all that’s needed for detection; no current
sensing is required.
In addition to occupancy detection, the system incorporates
some toggle switches to override signal aspects. The Annville
yardmaster has fascia-mounted toggles to control the east
and west approach signals entering the yard. Towns on the
main line have toggles that control approach signals to the
town. When the dispatcher gives a local train permission to
work, he instructs them to set the approach signals. The tog-
gles set the signal aspects to “stop” and also display a red LED
on the fascia.
