Always loved the Lionel B&O EM-1 2-8-8-4 with TMCC/RS4, but never liked the sounds or the jerky original Odyssey. Sent it off to Mike Reagan recently for upgrades, and he installed a new cruise control board, new sound board, a Super-Chuffer (4 chuffs per revolution), and repacked the smoke generator.
Results are spectacular! Now the operation is smooth as silk, the sounds are haunting, and the smoke will drive you out of the room. Thanks, Mike!
