20-3007-1 heavy pacific PS3 upgrade

Can’t help with the freight sounds but you can get flickering LEDs and just drive them off track power using a bridge and suitable dropping resistors. I use a a few orange and red LEDs to do this. Available on eBay for small money.

- The upgrade never had the firebox glow operational even though it was part of the original PS1 engine. Is there a way to hook that up?

Sound file I'll talk about separately.

The steam upgrade kit natively only supports headlight. Your PS2 engine should and probably did have a constant voltage board (6V regulator board for the incandescent and sometimes LED class lamps). The Cab light and firebox glow is normally left powered off of that constant voltage board. In fact, the upgrade instructions talk about this. Whoever did the install skipped that?

That said, that would not be flickering- just a red glow.

Notice the harness only has a plug for headlight.

Page 30 of the manual goes into adding the inductor for the boiler mounted constant voltage board that should have been left installed during the upgrade to power Firebox glow, Class LEDs, and Cab Lamp.

Example part

using a bracket like this to the top of the boiler shell

A search for Heavy Pacific and New York Central- all are passenger. So far I'm not yet successful in finding a different roadname heavy pacific with freight.

Norton and Vernon, thanks for feedback. Maybe after Easter I will open up engine to see if the constant voltage board is present. If not I might try Norton's suggestion. My hope is the board is still there and either not hooked up or bulb burnt out or not connected.

Regarding the sounds... I *think* the driving wheels on your loco scale out to around 71" and the gear ratio is 16:1.  This works out to around 0.28" per motor revolution, which is fairly close to a post-2001 RailKing Berkshire.

Now, I haven't messed with DCS sound and personality files in many years, long before they came up with "chain files", etc.  But... if you can find a suitable Berkshire with compatible electronics, it seems to me that a freight sounds file from one of those locos would come close to giving you four chuffs per revolution.  If you need an exact speed match for doubleheading, perhaps you could fine-tune it with a custom tach tape.  Please let us know if you try this and   whether it worked.
