At MPI, we are dedicated modelers capable of installing DCC and sound decoders in just about any type of motive power. We specialize in standard installations but can install decoders and speakers in brass steam, diesel or other types of power. Our knowledgable staff is also adept at adding current keepers, keep alives, no halt insurance or other forms of super-capacitor based onboard power with your decoder installation. Alternatively, we can add this new technology to your existing fleet of locomotives as well, boosting its performance to a new level. We can add or install LED headlighting and other lighting effects such a beacons or Mars or Gyra lights with decoder installations. We have a milling machine that allows us to mill frames for decoder installation. Drop us a line for a quote on installations or see the pricing page here on the site. Thank you for checking us out!
