Can't find the exact radiuses that you need in any of our pre-defined curved track assembly fixtures?

Not a problem! Simply enter the exact radius and track types (mainline, branchline, siding) that you need in the boxes above and we will create a custom curved track fixture for your specific needs. Note that custom built curved track assembly fixtures are premium priced, so wherever possible you should try and order pre-designed curved track fixture.

Trackwork built using Fast Tracks fixtures is NMRA compliant and will easily out-perform 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 curved custom trackwork that stays in perfect gauge - permanently
  • Performs Perfectly - Completely eliminates track related derailments
  • Is Easy To Build - No special skills 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

In addition to code 70 rail, you will also need to purchase matching 0.1" (2.5mm), (5 scale inches) thick, pre-gapped, On3 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.

To finish off your trackwork, add our Matching QuickSticks Crosstie Strips to your order. These laser cut, wood tie strips makes finishing straight trackwork a snap! We also offer traditional single piece wood cross ties as well. All of these additional items can be easily added to your order by selecting them from the options list on the upper right hand side of this page

Building curved trackwork using Fast Tracks tools and supplies is not very different than building straight trackwork and does not require any special skills. The only real difference is that the rail needs to be curved. To ensure that the rail is properly pre-bent into shape, we highly recommend that you consider including a Fast Tracks Rail Roller with your order. The Rail Roller tool will not only make it easy to create smooth consistent curves, but will also ensure that the rail is properly pre-bent so that it will retain its shape over time.

Fast Tracks Rail Roller

Use the Fast Tracks RailRoller tool to pre-bend rail used in curved track fixtures.

Failure to properly pre-bend the rail for curved trackwork will result in solder joint failure over time!

Note: We reserve the right to add any custom designed product to our standard product line using our regular pricing.
