A prolific thief who stole cable from the rail network causing damage estimated at £1.6m has been jailed for two years.
Stephen White, 37, targeted the rail line in Middleton, Leeds, on a number of occasions dating back to 2007.
British Transport Police (BTP) found railway property and scrap yard receipts for copper at his house.
White, of Bodmin Crescent, Middleton, had earlier pleaded guilty to eight counts of theft at Leeds Crown Court.
Det Insp Brian Buddo, from BTP, said: "White was a prolific thief who wrought havoc on the railway.
"He was reckless and single-mindedly driven by his desire for money, giving no thought to the risks he was taking, or the repercussions of his actions.
"The offences took place on one of the main railway lines in and out of Leeds, which carries hundreds of thousands of passengers each year, meaning that every time White committed an offence he was affecting a crucial public service."
Richard Lungmuss, route director for Network Rail, said: "This individual has caused significant disruption to the rail network across Yorkshire over many months.
"Thousands of passengers were inconvenienced by his actions and the rail industry is millions of pounds of pocket."
