I am considering retrofitting a "Keep-Alive" capacitor to each of several Bachmann HO model steam locos. Since I run some old models, I still operate on DC, not DCC My questions:
   Do such capacitors offer the same advantage to DC-operated locos as they do to DCC-operated locos?
   Some of my locos have DCC decoders and operate on either DCC or DCC; any specific cautions?

Any helpful comments, especially from personal experience, is appreciated.

I have never bothered with it. I use to run HO scale at home and the club. No one at the club used it. At home I had hand laid and the club had hand laid. We watched track cleaning and sometimes ran a John Allen track cleaning car.
My shortest was a 44 ton.
Below is a link about this issue. Decoder companies have different names for this device and some are now including it with some decoders. Some do not enjoy track cleaning it seems.

Very technical.

It use to be a single electrolytic cap, diode, resistor at one time.
