I got this from MTH several years ago on when they made the change from 5 to 3V boards. They actually checked each model number I gave them and told what each locomotive had.

Thank you for contacting MTH Electric Trains. We appreciate your interest in our products. I am afraid I cannot give you an exact date or catalog where we switched from the 5-volt ProtoSound 2.0 to the 3-volt system. For the Pr5emier engines (steam and diesel) in was primarily in the 2004 volume 1 catalog; the majority of the engines offered in that catalog or after have the 3-volt system. For the RailKing engines the switch over was about one catalog later - the 2004 volume 2 catalog. If you have engines that were released around this time we can check on a specific models.
