The Ulster & Delaware Railroad was a
heavily utilized regional railroad with a one-track mainline. To protect trains from one another, signals were used
to govern the movement of trains. Manual block signals, otherwise
known as semaphores, were installed at every railroad station on the
line in 1897 (with one exception, Grand Hotel Station
which had a manual electric train order signal). Previously train movements were
protected with a flagging system. The new semaphores were operated
by hand by the station agents. Automatic, electric, block signals
were installed by the U&D between the west
end of the Kingston Yard and the east end of the Phoenicia yard in
1907. This section was seeing an ever increasing amount of train movements,
especially in the summer months. The remainder of the railroad
retained the old manual order
boards.
