Suggestions for a power supply

<< < (2/3) > >>

nodcc4me:
Years ago, Ring used to promote their power supplies stating that you would not have to clean track as often as with others, including DCC power. I don't remember exactly why, but I believe it had something to do with filtering. I haven't actually read anything similar since the PWR56 came out, so I don't know if that still applies. My layout uses their PWR75 and I almost never have to clean the track. However, my test track uses the power supply I mentioned above, and although it gets much less use, that track has to be cleaned often.

Alan:
I believe I remember the Ring claim you refer to. I think that was versus DCC which is believable because of the square wave being pushed down the rails with DCC. Any momentary loss of contact disrupts the control signal. RailPro, just like any other DC power supply, has no signal waveform in the output. It is just plain ole straight DC current.

The inclusion of a radio repeater is what sets the RailPro power supply apart however, that has nothing to do with cleaning track.

I suspect the reason your test track requires more cleaning is due to limited use, not to the power supply. Wheels rolling on rails has a cleaning effect. The reason why layouts that see a lot of operation require less track cleaning than layouts used only occasionally, assuming everything else being equal.

nodcc4me:
That makes sense. And the wheels cleaning the track might explain why my wheels require cleaning more than the layout track, and deposit gunk on the test track.

Dean:
It could be that DCC runs signals to the engines through the rails. RailPro talks directly to the engine.

nodcc4me:
When I was a DCC club member, the rails and wheels had to be cleaned constantly in order for my RP engines to work properly. I'm sure it had to do with the signals through the rails.
