Someone at work was flogging a Scalextric Set called Caterham Clash. It was such a bargain it seemed rude not to buy it.
The two Caterham cars are in good working order but need a bit of TLC. They've both lost their rollcages so I'll see if I can get some replacements. When brand new they look like this:
As well as the cars, this has provided a load of spare track in excellent condition including the curves I needed to replace some of the cross-overs (so eBay will be seeing the brand new replacements I bought at the Hornby Visitor Centre last month). I've replaced the cross-overs at three of the existing points on the track but added one at Folly Carousel.
This seems to reflect alternative racing lines pretty well - come in wide, cut the apex and exit wide - or come in tight, run out wide, and then tuck in tight again.
Practising with a single car suggests this has sped up the laps a little (because the cross-overs contributed to de-slotting even without an opponent) but the real test will be next time I race against another driver. The track was delivered today, so unfortunately I wasn't able to test the new configuration with John and his son Tim when they came round yesterday for a racing session - along with some of John's cars from when he was Tim's age!
