Derry train forced to stop by adults drinking on the railway line

The PSNI said they stopped the train between Strathfoyle and Lisahally in order to remove people from the railway tracks.

Young people had also converged on the riverside railway.

Police said they had endangered themselves, everyone involved in clearing the line, and the passengers and staff of the train.

"On two separate occasions...members of our Local Policing Teams and Waterside Neighbourhood Team responded to reports of groups of people on the railway line between Lisahally and Strathfoyle.

"This follows several similar reports in recent weeks and months in this area, as well at Waterfoot Park and in the area of Station Road, Eglinton.

"Police located a group of adults drinking along the railway, as well a group of young people. Thankfully, our colleagues in the control room acted quickly and in conjunction with Northern Ireland Railway, they were able to slow and then eventually stop a train a short distance from these groups, to allow us to safely remove everyone from the line," the PSNI said.

Police at Strand Road urged people not to encroach on the railway lines due to the huge risks involved.

"We would like to remind people of the huge dangers involved in entering the area of any railway track or the banks of the Foyle. It is not an appropriate place to enjoy the sunshine or a good place to have a drink. It creates a massive risk to everyone involved in removing you from the area, and to the staff and passengers on the rail network," the force warned.
