9v was really the high water mark. There's a reason all model railroads use powered rails. 9v wasn't perfect, but it was very close. Many Lego modelers had already put DCC decoders in their 9v motors and this is the real opportunity TLG missed. Dcc would have opened up a splendid world of possibilities that have now been replaced with 2 channels and 7 speed steps. Really? That's an improvement? DCC would have gone a long way in legitimizing Lego trains with the wider model train comunity. Last year at NMRA when I told the OTHER train guys that the new Lego trains would be battery, they looked at me as if I'd ridden in on a horse. I'll hang on to my 9v, heck, PF works better on metal track anyway!
