Here in Syracuse, all the DC from Niagra Mohawk was shut off in 1952.
The buildings needing DC had motor generators installed at the
utilitiy's cost. I worked on many of the elevators and the MG sets. I
know of four of them, now dormant, that could be running and inspected
within a week. I am fairly certain Western Union took DC service until
1939, when the power system in the building was revamped in
anticipation of the war. The switchboards are still there in the
basement, about 99% dead now. The elevators were changed to 2 speed AC
control in 1939 as well. The top two floors of the building were active
with Western Union into the 1990's.
