hi whats the differences between w/Proto-Sound 3E+ and w/Proto-Sound 3 on mth steam engines ????
Quote from MTH web site
November 2011 - For those who have operated Marklin HO AC 3-rail trains in the past, choosing a Proto-Sound 3E+ equipped model will give you an opportunity to run sound-equipped North American and European prototypes on your railroad with your Marklin DCC command control system.
Outfitted with NEM 311 wheels and NEM 365 couplers, each of these engines feature an all-new version of Proto-Sound 3.0, contain a third rail sliding shoe for use with Marklin HO stud rail and can operate on European analog AC power. Like their 3.0 counterparts, Proto-Sound 3E+ locomotives feature full digital sound, speed control, 28 DCC functions*, hundreds of DCS sounds and features** and a command control receiver for use with Marklin DCC Motorola 1 and 2 control systems.
So it is the same sound system, just equipped to run onMarklin 3 rail
