MTH 50-1911 Proto-Sound 3.0 Steam Locomotive Upgrade Kit. Now operators can enjoy Proto-Sound 3.0 in older M.T.H. locomotives outfitted with M.T.H.'s original Proto-Sound or Proto-Sound 2.0. Other manufacturer's O Gauge and G Gauge locomotives may also be candidates for a Proto-Sound 3.0 upgrade kit (see the FAQ Section to determine if non-M.T.H. locomotives are upgrade candidates). Each kit consists of a Proto-Sound 3.0 circuit board, a coil wound Proto-Coupler, various wire harnesses, new speaker, new mounting brackets, and headlight and backup light bulbs. The kits are warranted for 90 days when installed by a participating M.T.H. Authorized Service Center. Each kit will require programming of a sound set prior to operation. The sound sets can be downloaded from the M.T.H. website at no charge but will require the DCS system in order to be uploaded into the upgraded locomotive. Virtually all features found in factory equipped Proto-Sound 3.0 locomotives are included in the Proto-Sound 3.0 Upgrade Kit. These include conventional and command mode Proto Speed Control, full Ps3 digital sound effects, DCS command features, conventional and command mode Proto-Coupler operation, conventional and command mode synchronized puffing smoke on locomotives equipped with fan driven M.T.H. smoke units, battery-less backup power and operating headlight control. Features Speed Control, Synchronized Puffing smoke, DCS Command Control and all the features that come with the latest command control system. Remotely controlled Proto-Coupler on the tender, PS3 Headlight control, 28 F-Function DCC Features and Battery-less Backup Power.
