Building and Maintaining Slot Car Tracks

    Page updated December 2020  

So you want to build a slot car tack?  How do you build it?

The techniques for building slot car tracks are much the same for any layout - be it a 2 lane track in your loft - a slot stocks oval track - a 4 lane club circuit or a 8 lane megga track.  Many of these web pages are based on my articles published in "Slot Car Racing News" , although I've added a number of new topics since. These pages include what I've learned from building 6 club tracks over the years, helping maintain all the various National Championship tracks since 1972 and  all 4 of the tracks used for World Championships in the UK and from talking to lots of other people (From  professional builders to people who have built one club track) ........... That certainly doesn't mean I know all the answers - you always learn something new when working on tracks -  if you have any better ideas or another way of achieving the same results then e-mail me  Thank you to all the people who have contributed information to the site.

I'm always happy to try and answer questions - and/or update this building guide. There's a Questions and Answers page for the questions that may be of general interest.

Many thanks to Rog Potter for the photos taken during the building of the Bournemouth club track which I have used for some of the illustrations on  these pages.

While much on these pages is applicable to digital lane changing systems and to HO tracks, I have not attempted to provide instructions for scratch building "digital" track or HO tracks.

For other track building sites including information on HO scale track building go to the  BSCRA links page.

Once the track is built it needs to be looked after, so have a look at tips on maintenance.
