Lights On at Morrison Hill Station

Eastern Mass. St. Ry. 4387 ( (Boston Suburbs) and Portland-Lewiston Morrison Hill Station at Seashore Trolley Museum

#4387 is stopped inbound at Morrison Hill Station. Note that lighting for the station is provided by strings of five light bulbs. Not obvious is that the bulbs are wired in series from the 600 volt trolley power. Thus when one bulb blows out, the other four also go dark. Conversely, when all of the lights are off, that is a clue that the trolleys are not running because the trolley power is off!
