The new Bachmann G Scale steam locos are equipped with a plug that allows the QSI Quantum Aristo sound decoder to plug right in. Unfortunately the Bachmann engines are wired a little differently than the AristoCraft locomotives.
If you use a QSI sound decoder with a standard G scale sound file in a Bachmann loco, the engine will go forward while the rear headlight will come on. Vice versa in reverse. We have solved this dilemma by making several sound files specifically for the Bachmann locomotives. They are:
- 3017-520 – Bachmann Forney 2-4-4
- 3017-552 – Bachmann K27 2-8-2
- 4004-749 – Bachmann 2-6-6-2 Logger
