...produced by Motorworks about 5 years ago. Picked up at a yard sale in like new condition---Sr's car was not even opened---they have excellent detail and very good paint, my son and I will be road testing them tonight.
They steer much like a real car, with both front wheels turning on their own steering points, the front end being fully adjustable...it simply amazes me how far rechargeable battery and micro-motor technology (the top picture being fairly close to actual size) have come in just the last 7 years....
UPDATE: The battery in Jr's car is toasted, leaving me free to experiment with it for future rail models, unless I find a source for replacement batteries.
The mechanism for steering is quite ingenious, using a rare earth magnet on the tie rod that is drawn to either side by small electromagnets.
