Bachmann 44950 Turnout Decoder: DCC Compatibility Guide
Product details verified October 18, 2026. Bachmann 44950 is a trackside accessory decoder that lets a DCC system operate one electrically powered turnout. The decoder sits inside a small HO-scale trackside building. Use the plug-and-play E-Z Track connection or the hard-wire method described by Bachmann. It does not motorize a manual turnout by itself.

What it does—and what it needs
The 44950 receives a DCC accessory address and operates one turnout through the layout’s DCC system. The turnout must already have an electrical drive and compatible connections. A purely manual turnout needs a suitable motorized mechanism before this decoder can operate it.
It is a turnout accessory decoder, not a locomotive decoder, signal decoder, multi-turnout controller, or general power supply. Plan one decoder per turnout unless the manufacturer’s current instructions specify otherwise for your setup.
Choose a connection method
- E-Z Track plug-and-play: Bachmann says to snap off the break-away tab and connect compatible E-Z Track connectors. Confirm the connectors on your powered turnout match.
- Hard-wire: Bachmann describes soldering the decoder to a control circuit board for advanced modelers. Follow the full wiring diagram and your DCC system instructions.
Disconnect layout power before wiring or changing connections. If you are unsure about the turnout motor, wiring, or DCC output, stop and check the instructions or ask an experienced modeler.
Compatibility: the decoder and the building
Bachmann lists turnout-installation compatibility for N, HO, On30, and O. The decorative trackside building itself is HO scale, so it may look oversized or undersized beside scenery on another scale. You can position the enclosure off-scene if the electronics suit your turnout but the building does not match the layout.
Installation checklist
- Confirm the target turnout is electrically operated and works before adding the decoder.
- Check whether the turnout uses compatible Bachmann E-Z Track connectors or requires hard-wiring.
- Confirm your DCC system can address accessory decoders.
- Disconnect power before wiring.
- Connect the decoder using the correct manufacturer instructions.
- Assign a unique DCC address and test turnout movement before restoring normal operation.
- Record the address in your layout plan to avoid conflicts.
