Well I managed to get some info about DYNAMIS from Bachmann they were giving out a nice little leaflet with an image of the control unit.
one of the feature that I'm looking forward to the most is that upto 20 points can be controlled from the main unit no point modules to worries about just wire up plug in and off you go, thats how it was put to me from the chap running the Bachmann DCC display.
There was no idea of the retail price.
But I was told that it is "100% NMRA compliant unlike another manufacuers system which could not be named"
and no other modification of points or other wiring.
