Build unlimited lengths of perfectly straight track with Fast Tracks Straight Track Assembly Fixture.

Part of the Fast Tracks Infinite Track System, this O Micro Engineering code 125, straight track Assembly Fixture can be used to construct straight lengths of mainline trackwork quickly and easily. Even though this fixture is only 16.5" (419mm) long, it can be used to make unlimited lengths of perfectly straight track! Once a section of track is constructed in the fixture, it is simply moved over, and the next section added. A single length of track with minimal rail joints can be built to any length needed by staggering the rail joints. Trackwork built using Fast Tracks fixtures is NMRA compliant and will easily outperform any store bought track! No special skills are needed, and results are guaranteed. Fast Tracks assembly fixtures will help you build high-quality hand laid track that:

  • Is Highly Accurate - Build straight mainline trackwork that stays in perfect gauge - permanently
  • Performs Perfectly - Eliminates track-related derailments
  • Is Easy To Build - No special skills are needed
  • Looks Great! - Get results that rival even the most experienced modelers
  • Lets You Work in Comfort - Build trackwork at your workbench
  • Is NMRA Compliant - Will work with any NMRA compliant equipment

Additional Items

In addition to code 125 rail, you will also need to purchase matching 0.0625" (1.6mm), (7 scale inches) thick, pre-gapped, O CopperHead PC board Crossties manufactured by Fast Tracks for curved and straight trackwork. Our PC Board crossties match the thickness of the wood ties and are pre-gapped for DC and DCC compatibility. Add our matching QuickSticks Crosstie Strips to your order to finish your trackwork. These laser-cut wood tie strips make finishing straight trackwork a snap! We also offer traditional single piece wood cross ties as well.

    As always, great way to lay track. I have also used it to make easements, by soldering one rail, installing and then soldering the other rail. OUTSTANDING. Thanks
