Actually, for a complete job with fan driven chuffing smoke, you'll need the following.
- ERR Cruise Commander (the DC is implied, there is no cruise for AC motors)
- ERR RailSounds Commander (choose the sound set on the ERR website)
- Fan Driven Smoke Unit (I use MTH steam smoke units, but a Lionel smoke units work as well)
- Super-Chuffer II (controls smoke chuffing and adds lighting features)
- Chuff-Generator (generates programmable synchronized chuff pulses based on driver revs)
Let me know if you have any questions as I'm sure you will.
