The Lionel 6-12025 is a 4-1/2" straight track section from Lionel's FasTrack system — the easy-to-assemble three-rail O gauge track that's been the backbone of Lionel layouts since 2003. This shorter straight is a perfect filler piece for tight spots, custom layouts, sidings, and yard ladder arrangements where a full 10" straight is too long.

About FasTrack
FasTrack is Lionel's modern O-gauge track system, designed to look great straight out of the box with realistic gray ballast and dark-tie detail molded into the roadbed. The track snaps together with built-in connectors — no separate track pins to fumble with, no roadbed to add later. FasTrack is fully compatible with all Lionel O gauge locomotives and rolling stock that run on traditional tubular O track, including conventional transformer control and TMCC/Legacy command systems.
FAQ
Will it work with Lionel O27 trains?Yes — FasTrack is O gauge, and most O27 trains will run on it. FasTrack curves are O36 minimum, so very small O27-only locomotives may not navigate the tightest curves, but straight pieces like this 4-1/2" work fine with anything O gauge or O27.
Can I mix this with traditional tubular O track?Lionel makes adapter pieces to connect FasTrack to tubular O. The adapters are sold separately.
Why use a 4-1/2" straight instead of a 10" straight?Short straights are essential for fitting yards, sidings, and tight spots into your layout. A 4-1/2" piece lets you adjust spacing in increments smaller than the standard 10".
