TCR (Total Control Racing) TCR !!!
I used to assemble these in my student summer holidays at the Ideal Toys factory in Wokingham, I spent the 1st few weeks electronically timing the cars on a 40 foot length of track to ensure that an evenly matched pair of cars was put into each set. We also used to put the metal contacts into the tracks by hand - EVERY SINGLE RAIL - best fun I ever had for £52.10 a week at 16 !!
