I think it’s a shame that egos, corporate pride, and corporate greed have resulted in 3-rail operators being forced to use several different, unwieldy, and incompatible digital control systems. It’s a system of forced brand loyalty, and it is very short-sighted.
The HO scale manufacturers realized a long time ago that what was best for long term survival of everyone in the business was to adopt a standard digital control system (the NMRA Standard DCC System) across the board.
Sadly the die is now so firmly cast in three-rail that we’re stuck with systems that are loaded with silly gimmicks and far too many buttons on the controllers, but are very short on reliability, easy installation and basic functionality for just running trains.
