Sure can.
Even a straight old DC layout can catch fire. A DC transformer does have a built in breaker that cuts out on a short. (remember when the red light on the xfmr would come on?)

You would need to have the short and then constant power feed. You have probably experienced a DC short at some time, and Loco gets hot and you smell a melting situation ... eventually it could flame up. It's kinda like a toaster wire turning red, can burn something.

Railpro puts out 14.7v and about 5 amps ? Enough to cause a problem if left in short stage.
Ring makes the CB-1(circuit breaker), someone can explain how they work .. I have not installed mine yet. Not sure if they cycle on/off like dcc ?

Ken,  Not as hot as last week but mid 95 degrees this afternoon...  It's a dry heat.

Just collected too much over the years..  Huh !    Some lightly modules and a lot of other stuff like iPhone speakers, cubes etc. Not going to sell bits and pieces so there will be lot item of like kind. First listing will be here this week. cheers TOF in Yuma. Ya it's getting warm...

Hello All you Railpro Brothers and Sisters ! Happy Spring !

Just kicking can down the road, anybody know where to buy RP Modules lately ?

SSS website shows no stock, and I emailed him about availability,
Let's just say he did not sound too enthusiastic about selling RP. - He did not say he wouldn't, but ...

Just checking the waters before purchasing my next batch of LMs. Never hurts to compare notes.
If anybody has a surplus they want to off load - (prefer un-used) ... reach out to me.

Thanks
Pat

I think there was a subject like this recently that I remember answering.

Railpro power puts out 14.7 v (dc), so it is on the high side. But as you stated - seems to work.
You could also power it with an old Tyco or other standard DC xfmr from past train sets if you have any.(?) - and dial the voltage back to 11 or 12v for a lower output, plus not taking anything away from the rail power system, if it happens to short again, may run the risk of messing up a module, or other RP equipment since it's all connected from track ... just a thought.
