Description
The Circuitron 5401 AR-2 Automatic Reverse Circuit with Adjustable Delay is the AR-1 with an added adjustable delay timer — train pauses at the end of each run before reversing, just like the prototype pulling up to a stop.
What it does: Same auto-reverse function as the AR-1 (5400) but adds a user-adjustable delay between triggering and direction change. Adjustable from a few seconds to ~30+ seconds — long enough for a passenger train 'station stop' or a mine-load swap.
- Trigger: Opto-Sensor (covered) or external pushbutton
- Delay: User adjustable
- Power: 12 V DC input
- For: DC point-to-point with realistic 'station stop' pause
- Circuitron SKU: 5401 (Walthers 800-5401)
Tip: Use a long delay to simulate a freight-yard switching pause, or a short delay for continuous trolley-line back-and-forth.
About Circuitron: A USA-made model-railroad electronics specialist (Maryville, Illinois) founded in the 1970s. Famous for the industry-standard Tortoise slow-motion under-table switch machine and its surface-mount cousin the SMAIL. The full range covers detection (block detectors, Opto-Sensor grade-crossing logic), automation (auto-reversers, external relays, twin-coil alternators), signal / lighting electronics (alternating flashers, ditch-light oscillators, strobe drivers), power supplies, and a complete set of Tortoise / SMAIL replacement parts plus the solderless ZipZ connection system. Most circuits work with AC, DC, or DCC track power unless specifically noted otherwise.
