Is anyone aware of the law when it comes to items abandoned or left behind when a company gets liquidated?

I live near a former railway sidings and yard which has laid untouched in any capacity for nearly a decade. There looks like there are several tons of coal there, I've established that the previous owner of the yard was liquidated and the land couldn't be sold as planning permission wouldn't be granted and it failed to sell as a yard etc.

Is the coal fair game?
