I picked up a MTH 0-8-0 at a swap meet recently. I owned one of these back in 1986-1990 when they were first introduced. This version has bells, whistles, choo-choo, and talking. I am old school and find these "distractions' irritating. I am thinking of having a friend, who is an aircraft electrican alter the wiring in the tender so the speaker can be turned off. That way if I sell this later on all the that noise will still be available and the battery will still be charged! Does that seem reasonable?
