TCR was manufactured by ideal in the late 70's to early 80's.
TCR (Total Control Racing) was a slotless track system that gave you more control over your racing cars than ever before. Because there were no slots for the cars to fit into like Scalextric, the TCR cars could change lanes. This was done by flipping a switch on the Hand Controller. However when the cars came to a bend they would always default to the outside of the bend due to gravity and centrifugal force. This meant that you could not overtake on the inside of a bend, something that was perfected by Matchbox's Lanechanger racing system.
Most TCR sets that were sold came with the added bonus of a third vehicle, a Jam Car which travelled at a slightly slower speed than the two "racing" cars. This meant that in order to win a race you would have to negotiate this vehicle as well as your opponent.
Some sets also came with a articulated truck that you had to race in order to win.
