The Digitrax SE74 is the signal and turnout decoder that ties a working signal system to your LocoNet. It drives signal masts, throws four turnouts, reads eight input lines for sensors and local push buttons, and stores eight routes of eight entries each - which means interlockings and crossovers can be set from a single command instead of one turnout at a time.

What else do I need to get signals running?
The SE74 plus signal masts and a way to carry the connections to them. Most installs use a Signal Driver Cable Kit (SDCK) for the ribbon cable and sockets, plus mast bases and mounting hardware. You also need occupancy detection - the SE74 displays aspects, it does not detect trains on its own.
Can it drive slow-motion turnout machines?
Yes. The four turnout outputs are configurable for either solenoid machines such as Peco, Atlas and Kato, or stall-motor machines such as the Tortoise.
What are routes and why do they matter?
A route sets several turnouts at once from a single command. With eight routes of eight entries you can line an entire crossover or interlocking with one button press instead of throwing each point individually.
Do I need a Digitrax command station?
Yes for full configuration - the SE74 is a LocoNet device and is set up over LocoNet, with the most convenient programming from a DT602 throttle.
