I own the MTH 4-6-0 Steam Freight R-T-R Train Set w/Proto-Sound 3.0 (30-4215-1).  I would like to install a flickering fire box and two green marker lights in the 4-6-0 Steamer. 

 

Within the locomotive, are there powerports on the DCS Board that I can splice into for power?

If so, what are the output voltages?

Do you run conventional or command?

 

Unless you want to attempt to control the markers, I just use track voltage.

 

For the flickering firebox, I buy the LED tea candles from a Dollar Store and remove the flickering LED, cheapest source I've found.  They work great for the firebox, gives you the flickering effect for no effort, just a diode, capacitor, and a resistor from track power.  You can power the classification LED's the same way.

 

A 1N4003 diode, a 220uf 35V capacitor, and a 1K resistor will power the flickering firebox LED.  Use a second 1K resistor from the same diode/capacitor filter for the classification lights, wire them in series.

 

 

Well, the short answer is, it's difficult and maybe impossible, depending on the actual installation.  That's why I asked.  I'm not familiar with the wiring on the PS/3 stuff, but for PS/2, the sound files control the functionality of the various functions, and if they're not in the product, you usually don't have that control.

 

The simple way is to just run them from track power.  It may be possible to trigger them from the headlight, but I'm guessing you'd need some electronics as I don't know what kind of power you can draw.  You could probably run the firebox from the smoke unit power, that way the firebox would only flicker when you had smoke working.
