    I'm fitting a beacon to my HO SW7 303 to represent the one on top of the cab in this photo.
    How did these beacons light?
    In other words were they rotating beacons, stratolites, flashing beacons or did they stay lit when turned on.
    Thanks in advance for any help.

    In the photograph example you posted the lamp is constantly illuminated.

    Basically it is a standard screw-in type light bulb (24 volt) covered by an amber glass dome. They were controlled by an on/off slide switch on the electrical cabinet inside the cab. The switches were sometimes later removed to prevent crews from turning them off when in service.

    This type installation was common on our early, first generation switch engine locomotives.

    Hope this helps.

    Hi Mark,
    Thanks very much for your advice.
    I really appreciate it.
    I'm also doing an SW1500 that has what looks like a rotary beacon on the cab roof.
    Were these also constantly illuminated or did they rotate or were they stratolites or?
    I'll post this on the SW1500 page as well.

    Thanks again for the info on the SW7.
