Lionel 6-12020 | FasTrack Remote Uncoupling Track - 5" Straight Section | O Gauge

Lionel FasTrack Remote Uncoupling Track — a 5" straight section with a built-in electromagnet that lets you uncouple cars anywhere on your layout with the press of a button. The roadbed and pin connectors match the rest of the FasTrack system, so it drops right into a yard ladder, siding, or industry spur without any custom wiring on the rails themselves. A button on the included controller activates the magnet to release the coupler when a car is positioned over the section.

This piece is the cornerstone of any switching layout — let your operator set out cars at customers and pick them back up without ever touching the rolling stock. Browse our full O Scale Track & Accessories and O Scale Trains & Track to round out your FasTrack system.

• Built-in electromagnet uncouples Lionel-style magnetic couplers on command — no manual handling needed.
• Standard FasTrack profile with molded gray roadbed and pre-attached ties matches the rest of your FasTrack layout.
• Includes push-button controller and lockon for quick wiring; runs off track power or a fixed 14V AC accessory supply for stronger uncoupling.
• Half-straight section included for fitting the uncoupler into a standard 10" track block.
• Snap-together pin connections lock securely with no extra rail joiners required.
• Scale: O Scale (1:48) — three-rail O Gauge.

Will this uncouple any Lionel car?
It uncouples cars equipped with magnetic-style couplers — that includes virtually all modern Lionel rolling stock. Older non-magnetic couplers and Kadee couplers do not uncouple over this track.

Does it work better off track power or an accessory supply?
Both work, but a fixed 14V AC accessory supply gives the strongest, most reliable uncoupling pulse — especially at low throttle where track voltage can drop too low.

Why is a half-straight included?
The uncoupling section is 5" long. The included 5" half-straight pairs with it to fill a standard 10" FasTrack block, so you can drop it into an existing layout without re-laying track.

Is this compatible with Lionel tubular or American Flyer track?
No. FasTrack is its own roadbed system. You'll need a FasTrack-to-tubular transition piece if mixing track systems.
