In 1961 engineers were already planning the Chunnel. Here they used a OO model railway to show the action of the trains to and from France and the automobile carrying capability. The cars are electric and can move on their own like race cars did (or do today). Really neat and boy this would have been a fun job to have.
I wonder if any of these guys are alive today since this took place 51 years ago - when I was born.
