Just had info on the New Le Mans track pack from Tecnitoys.
It includes the Le Mans start (as last year) but also a 'X' cross over section to allow for four lane starting.
These items seem to go for mad prices on Ebay (not anymore?).
The bad news? - Spain only (at this time).
Can't grab a photo from their web site, but go to www.scalextric.es and check the new section.
