Just picked up the WBB E-7 in the NYC livery-what a monster! Installed an MRC sound card in the dummy where I also relocated the speaker. Programmed the card and now I have a beautiful A-A unit with sound I can operate on my conventional loop with my MTH DCS remote. The sound is very good must be the roomy dummy cab with all those photo-etched screens to emit the sound through. Really feel these A-A units are a great bargain, think I'll go for a F-7 set next(Great Northern,perhaps!).
Thanks, Williams, nine WBB engines and counting...

Hi all this is my first post here. Just picked up my new Penn GG1 loco Item#41797 and an O-27 four car passenger set. Super price and the quality of the GG1 is awesome. Wired the motors in serial and put 2 LED bulbs in the engine and it looks and runs super!! This is my second WBB engine (got a B&M BL2 last week) and I predict there will be many more. Am running a conventional outer loop and MTH DCS on the inner loop talk about having your cake and eating it too. Thanks Bachmann,
nice to have another option without sacrificing quality...
