Would Bullfrog Snot (yes its a real product) help the OP?

The one that I have has an on off switch in the cab I just shut it off.

Yes I have it on the back of a string of Tropicana reefers.

I believe master volume for sound value is CV 128 but I am not surer how to set it to silence.

I have one of those Bachmann EOT devices they work fine in DCC.

The GP 38-2 is my go to Locomotive.  I suggest the Sound Value model if you run DCC. Very smooth running.

I don't think that's possible but I would remove the incandescent lights anyway as I think LEDs especially if they are white will look more prototypical. By the 70s and 80s subway trains were bright florescent.

Thanks that should be plenty of time,

Len;

Thanks, I may order the easy peasy system for my birthday next week.  Do you happen to know what battery it uses.

Well I was thinking that the first thing I should do is time the blackout periods.  10 to 20 seconds seems like a long time to depend on a capacitor. Plus not being that well versed in electronics I have no idea what capacitor to buy.

I think then I should solder it between the lead to the bulb is that correct? They are regular incadescent bulbs(though while I have the Top open maybe I should convert it to LEDs?).

Len could you be more specific about those light boards.  Who makes them?

I have this product and it works quite well for my subway display except for one issue when the subway reaches the end and the power cuts it turns off the lights in the cars.  Wondering if any has made a keep alive circuit for lighting?

ACY thanks as I said I was not sure.  The GG1 era was mostly before my time.

I am not sure but I think the reason that Conrail only had 1 GG-1 is that they kind of got stuck running commuter rail in NJ before NJ Transit took over.  I think GG-1's we're mostly in passenger service on The Northeast Corridor Am I right?

Wiley:

Long time no hears. Hope all is good

If your last post was supposed to have pics I can't see them

Why can't it be both I have a circle of Lionel Track I can setup iif I want to see a train run in a circle.  A point to point switching layout in HO and an automatic reversing subway display.
