WOW, i am surprised about the weight. i don't have any of the Genesis line, but my old ones are as heavy as bricks. emt49, tell me, does the Genesis line come with DCC? thanks, -Dean
I think you have to swap out the board on the Gennie SD70s. The TCS A6X (I think that's the one) has built-in resistors so you don't have to do a bulb change.
