The CN-GP is a N-scale drop-in decoder for Atlas, Kato, and Life Like locomotives. Examples include the following:   Atlas: GP7/GP9 GP30/GP40/GP60   Kato: SD40   Life Like: GP18 GP60   See the Installations Page for a full list...

The LokSound 5 Fx is a special feature of the LokSound family: it has no output and is specially designed for use in control cars or drive heads, which require a sound but do not have a model drive themselves. By omitting the engine part, it can still...

 The LokPilot 5 Nano DCC is the “twin” of the LokSound 5 Nano DCC. At 19.6 mm x 8.5 mm and a thickness of only 3.2 mm, it is exactly the same size as the corresponding LokSound decoder, but does without the sound functions. The LokPilot 5 Nano DCC...

HO-scale, 4-function decoder that measures 74 x 17 x 3mm designed to replace the existing manufacturer light board in Atlas HO diesel models, some InterMountain Railway models, and those using a similar physical design. This decoder will operate in both...

HO-scale, 4-function decoder that measures 25.1 x 15.6 x 4.7mm. This decoder has a 21-pin connector arranged according to the NMRA Standard that easily plugs into the factory-installed PCB of many models. This decoder will operate in DCC...

 The Decoder Buddy Mini was developed to fit into smaller steam and diesel applications.  There has also been interest in HOn3 and S-Gauge applications. 

With its unique design LokSound 5 DCC Direct, with integrated PowerPack can easily replace boards that provide poor motor control, low volume, or generally inferior sound. Not only will the decoder work fine with most factory installed speakers, but it...
