Tried all four systems here over the years. That's DC, DCC, RC and live steam. Currently run live rail DC for "her" locos which are mainly LGB. Run RC both indoor and outside. Found DCC expensive, irritating and still has the major disadvantages of track cleaning. DC can be a real pain when cabling up the isolating and secondary feed extensions/modifications etc. RC is convenient, cheap, easy to install and set up and with the new battery packs and small profile kit is improving in leaps and bounds. Live steam, is expensive, still requires RC unless you enjoy chasing locos, needs more in the way of general servicing and can be very messy. Live steam and live rail running do not generally go well together as clean track and oily locos with any sort of incline involved can be very interesting indeed. So based on our experience RC, steam and DC here, where for some strange reason I usually end up cleaning the track for her to run her live rail stock. One remaining disadvantage to our current system is that we have to run all insulated axle stock to avoid shorts when using live rail.
