FAQ
Which locomotives does this kit fit?It's designed for ScaleTrains HO diesels including the EMD GP38-2, GP40, SD7 & 9, SD40-2, and SD45, plus GE Dash 8-40C, Dash 9, and ES/ET/GEVO/Tier 4 models.
Does it come with a decoder?No. The kit provides the Decoder Buddy motherboard, keep-alive, and speaker. You supply any standard 21-pin sound decoder of your choice.
What does the Power Bridge III do?It's a keep-alive circuit with two 1.0 Farad super capacitors that stores power to prevent sound dropouts, light flicker, and stalling on dirty track or turnouts.
Do I need to solder?Installation is largely plug-and-play thanks to the 21-pin Decoder Buddy, though basic hobby soldering skills are helpful for the speaker and keep-alive connections.
