Yobs with hacksaws caused nearly 100 commuter trains to run late this week after they struck in the early hours of the morning.
Police revealed the vandals used the tools to cut cables, acting at around 6.30am on Wednesday, January 13.
The damage resulted in delays to 91 trains, said British Transport Police, who are looking to speak to anyone who can help their investigation after railway signalling cables were cut along the Denaby side of Conisbrough railway station (pictured), on the Doncaster to Sheffield line.
Investigating officer Detective Constable Andy Lehman said: “A hack saw was used to cut through line side signalling cables which resulted in a loss of power to signalling in the area.
“This caused 91 trains to be delayed with the damage taking several hours to repair.
“Mindless acts of criminal damage like this result in a huge amount of disruption to passengers as well as the inevitable cost to the industry to repair the damage.
“Anyone considering such reckless behaviour should also bear in mind that the railway is a dangerous place and they are putting their lives at risk by trespassing near the line.”
