c.sam - FYI, K-Line's 2004 First Edition catalog actually shows three (3) B & A Scale Berkshire engines, one of which is Green while the other two are black. To assist you the item numbers are as follows...
1. Green version K3670-1426CC (#1426) with Lionel RailSounds, TMCC, Cruise Control
2. Black version K3670-1407W (#1407) with Cruise Control, Whistle & Bell only
3. Black version K3670-1407CC (#1407) with Lionel RailSounds, TMCC, Cruise Control and Electrocoupler
Good Luck in finding one!
P.S. I actually have the Green B & A and it's a real smooth runner, although I'm not interested in parting with it at this time.
