Maybe someone can help me - i want buy MDT Plymouth with new, silent motor new, silent motor, but not understand how to found them.
Trader say - "You need found 5-digit identificator". I see in  Bachmann store - five MDT Plymouth with different numbers (one o them i now have, but no success - old noisy motor inside).
How to identify MDT Plymoth with new can motor?

Really GP7 locomotive is most silent? Or switcher NW2 are quieter? Maybe another locomotive are better in this case? Maybe somewhat is GP7 owner an can tell real situation?
