Number, please?
This telephone has multiple switches and lights. Each button is for a separate line. I hypothesize that the first line is for the train dispatcher. The second line is for Landover, the tower south of Bowie. The third line is for Odenton (and later Grove tower when Odenton tower closed.)
When the switch was flipped down, the operator could converse.
All the towers on the line (Landover, Bowie, Grove, Gwynn, and B&P) could simultaneously listen on the dispatcher's line for train movements. The information heard on the line was conveyed to the northeast corridor train control log sheet. (Photo 7.)
The white button indicated that somebody was calling. The red button indicated the Bowie operator was calling somebody else.
The operator talked into the "hands free" phone on the left.
