for dcc operation, be mindful of lighted cars and other operating rolling stock on DCC operation, the car top will become warm, due to the lights constant operation on DCC current, it should not harm the whole acela train!!!!

i know about that but when the lights are dim in the room, you can gain a 3 additional feet. when i get my dynamis pro system, i can run trains from my dynamis and my home PC. later talk..
