London Underground’s experiment with a carpeted tube train

Fifty years ago, the London Underground put a carpet on the floor of one of their tube trains to see what the public thought. The verdict was not favourable.
At the time, tube train floors were made of slatted wood, but London Underground faced a problem. The floors were usually made from hard-wearing Canadian maple, but in the 1970s, there was a growing shortage of Canadian timber, and prices for what they could get were soaring.
