Just got my new RailKing Wheeling & Lake Erie SD45 and put it on the layout and played the extended start up sounds and near the beginning the crew member has a case the chipmunk voice. While that will probably bother a lot of people I found it to be hilarious and I don't really intend on getting it fixed even if it can be. Anyways I hooked the engine up to my Weaver 3 bays and MTH 4 bays and it runs great.
