Nexus, which owns, manages and is modernising Metro, is starting work this week on the replacement of the passenger lifts at Heworth and Four Lane Ends interchanges.
The work will see the passenger lift cars replaced with brighter, cleaner, quieter and more energy efficient technology.
The work will be carried out in phases so that both of the interchanges will always have at least one passenger lift in operation.
Nexus owns and manages the Heworth Interchange in Gateshead and the Four Lane Ends Interchange in North Tyneside.
The lifts on platform one at both interchanges will be out of action from this week until September. The respective lifts that serve platform two will be replaced between September and November.
The work forms part of the £385m Metro all change modernisation programme which will see the network transformed over the next 11 years, including new-look trains and refurbished stations.
Director of Rail and Infrastructure for Nexus, Ken Mackay, said: “The replacement of passenger lifts is a vital part of our £385m Metro modernisation programme. New lifts vastly improve the overall passenger experience.
“There will be some disruption at Heworth and Four Lane Ends while this work is carried out and I thank passengers for their patience while we get on with this project.”
Monument and Central Metro stations in Newcastle city centre are both set to undergo escalator replacement work in the coming months. A total of eight new escalators are being installed with the work scheduled for completion in March 2013.
