 Hi Folks, you must be puzzled by now, where are those results 

The truth is that after spending even more time on the D Class cars this morning, we was already for action just after lunch. My wife was poised with the Mobile for some video action.

Then bugger me the cars would not go for more than 7 laps before coming to a grinding halt, so as you do thought this was a car issue so I tried another C class car, and that refused to go as well. So I tried my own Class A & B cars, and they refused to run more than 7 laps.

Well I have replaced the transformer, then the controller etc, but still NO GO 

By this time I have pulled all my hair out and decided to call it a day, whilst I contemplate what to do next. I can only think the problem is related to the connection box fitted to the track

And bad news for Pip, This morning on an unrelated issue I was still having contact issues with his Fiesta , so I changed the guide but still no improvement 
and to cap it all the passenger lost his legs and a front wheel fell off (glued back on now) during the session.

So you can see I not had a good day.

Anyway hopefully tomorrow morning I will replace the connecting track piece with something different (about the only thing I not replaced now), I have a Scalex Sport connecting track and some classic track adaptor pieces which should work.
