Holy shit - I had that Tyco set. Was a huge xmas gift to me and my little brother. It was an amazingly good track, but it took a while to setup and make sure all the connections on each piece of track were carrying current. This usually mean getting shocked while you tried to figure out why the cars would suddenly skid to a stop on a straightaway.
The cars went waaaaaaay too fast, and they were only connected to the track by the thin copper peg on the bottom of the chassis, near the front wheels. This meant they would fly off the track the moment you hit the controller too hard on a curve, and the controllers were insanely sensitive.
Many crashes, many shocks. Good times.
