I'm not considering buying this for myself, but researching it.


The Rail Pro system made an O scale decoder, now labelled O / G... but no mention at all of constant current output, momentary current capability, nor max voltage.


Can anyone give any information?

Thanks K, i was interested in sound sync for chuffs in steamers, etc.


The user group will be a good place, especially since it is independent.

Hey Greg


I have installed RailPro LM3g units in all my locos (6 so far). I got them from Remote Control Systems of New England. Don Sweet runs the shop, and he is very knowledgeable indeed when it comes to RailPro. I'd give him a call and ask him (603) 321-1347.



I did the install on my locos, I found it a little tedious, but enjoyable. The results are fantastic - operation is excellent, sound is phenomenal and the joy of not having to clean the rails is beyond belief great.

RailPro Specs

Hi Greg, you are correct there is no chuff trigger wire. The plan is in the next version will activate the purple wire for the chuff input. This will be a software download.

Also the steam sounds will get a upgrade to the UTL files. Most of the diesel and horns have been updated.

The LM-3S-G loco module is rate at 6 amps continuous and 8 amp stall current. The audio amp is rated at 13 watts into 4 ohms and 7.4 watts into 8 ohms. It can be very loud!!

That's a nice spec for the amp, in large scale you can put a pretty big speaker in the loco and bass will use wattage... I actually got a 4.5" speaker in one of my Accucraft tenders...

Note that visiton Frs7 and Frs8 speakers are available in 4 ohm and 8 ohm versions as are several smaller sizes.

Yep, my setup in the USAT PA diesels has 4 speakers, 2 tweeters beaming out the grills behind the cab, and one in the fuel tank, and the other beaming up out the rear fan.


In both cases, used two 4 ohm speakers in series to give 8 ohms to the sound card (2 channel sound from QSI)
