Metro passengers are being warned of forthcoming line closures as part of a multi-million pound scheme.
Nexus, which owns and manages the system, is replacing 8.7km of Metro track in North Tyneside which are more than 50-years-old.
The first major line closure will take place from Saturday, March 19, to Saturday, April 2, with the lines closed between Tynemouth and Shiremoor.
The second line closure is scheduled for Saturday, July 23, to Saturday, August 6.
Raymond Johnstone, director of rail and infrastructure for Nexus, said: “This is the next major piece of track replacement work in our £350m Metro modernisation programme.
“We are replacing tracks and track beds which are more than 50-years-old on Metro’s North Tyneside coastal loop. It is a once in a generation piece of work to ensure Metro is here for many decades to come.
“The work can only be done by closing lines. There will be two major line closures taking place.
“Each closure will last for fifteen days. We will also be working over a number of weekends and at night. The work is absolutely vital.
“During each closure we’ll be working round the clock but we will do all we can to keep the disruption to a minimum.
“When the lines are closed customers will be provided with a frequent replacement bus service in the affected area.”
Modernisation works on the line will also take place during a series of weekend closures and also at night, during Metro’s track access hours.
A total of 3.8 kilometres of track will be replaced between Monkseaton and Cullercoats during the March major line closure.
Then another 3.7 kilometres of track will be replaced between Monkseaton and Northumberland Park in the July closure period.
A total of 8.7 kilometres of track will be replaced in North Tyneside during 2016.
Nexus has already sent letters to over 3,000 households in North Tyneside to make residents aware of the forthcoming works. It will also carry out public drop in sessions for people to find out more about the project.
Nexus previously replaced six kilometres of track between Wallsend and Tynemouth during 2011 and 2012.
