Its perhapse more prvalent now than before, but way back in the 1970's A factory where I worked was built along side an old railway branch line. Disused for many years since the wonderful Dr Beeching closed it, but itv still had the tracks. One day a fleet of contractors lorries arrived with tractors and hoists. They were there for about two weeks as they proceded to cut and lift about a mile of track.
They cleared up and went away. A very neat job with all the safety signes.
A few months later a bemazed Bitish Rail offical came to our reception and asked if we know what had happened to their track!
