Where are these squareheads?

If anyone wondered why steam is shown apparently being exhausted by the electric locomotive in this picture, a probably explanation is that it is a result of the liquid rheostats that were used to control the current flowing to the traction motors during the acceleration of the locomotives to their synchronous speeds of 14 and 28 mph. The heavy current passing through the liquid heated it considerably, and the liquid had to be cooled, so it was circulated through a cooling tower in the locomotive carbody where some of the hot liquid vaporized and was vented as visible "steam."

Can anyone locate where this photo may have been taken?
Not only do we have a semaphore on the first Catenary support, but there also appears to be one on the fifth support also.
Could the Bluestone River be just off camera left?
