Note: If you are upgrading a PS2 engine with Operating Pantographs then order 50-1911..

FEATURES

  • Speed Control
  • Variable Intensity Diesel Exhaust Smoke
  • DCS Command Control and all the features that come with the latest command control system.
  • (2) Remotely controlled Proto-couplers
  • PS3 Headlight control
  • 28 F-Function DCC Features

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 smoke on locomotives equipped with fan driven M.T.H. smoke units, battery-less backup power and operating headlight control.

M.T.H. strongly encourages consumers to utilize the nationwide network of M.T.H. Authorized Service Centers for installation of the Proto-Sound 3.0 upgrade kit. Upgrading a locomotive to Proto-Sound 3.0 may require significant rewiring of the locomotive, installation of new mounting brackets, soldering and careful wire management to prevent pinched wires that could damage the circuit boards. Consult a participating M.T.H. Authorized Service Center for installation costs. Cost are estimated to range from $150.00 to $200.00 depending on the locomotive.

Grille-ing Me Softly: A 30-Minute Makeover Adventure
Color: Single Slat Gloss Black, Size: 2019-2022 G20, Color: Single Slat Gloss Black, Size: 2019-2022 G20
Installing this grille was a breeze! It took me about 30 minutes, even with a minor hiccup of having to uninstall it to add the front camera panel I initially forgot. The grille feels incredibly durable, made from plastic that matches the quality of the OEM version. Plus, it gives my car a fresh, youthful look. Highly recommend for a quick and stylish upgrade!
