I've seen some CAD drawings of the new Bachmann J72, and it shows lamps in the express passenger postion, are these going to be seperate details or part of the body moudling (there may already be a post disscussing this loco, but i couldnt find it)
Beside the progression of Model railways it is a progression in general! As these motors use less current and are more efficient they are catagorized as "green Motors" or environment friendly motors and thats where investors & banks want to put money in. This is why it is changing so fast and it has nothing to do with model railways but with the reduction of energy consumption and that is why several old motor types (Including some of your favorite Model railway motors) are simply pushed out
