Preparation works for the substations, which are being built on Metrolink park and ride sites at Brooklands and Whitefield, will begin on Wednesday 29 March.
To accommodate the works, from Monday 3 April, 25 parking spaces at Brooklands will be temporarily out of use and 16 at Whitefield.
Following the works, which will take between six and eight weeks’ to complete, there will be 10 fewer parking spaces at Brooklands and seven at Whitefield.
However, customers using the park and ride sites will still benefit from more than 300 free spaces across both locations.
Along with a recently installed wheel lathe at Trafford depot, a new ‘turnback’ at Sale and 16 additional trams, which are now running on the network, the £44m improvement package will enhance the capability of the network, increase resilience and improve operational reliability.
Between Sunday 30 April and Monday 1 May and Saturday 13 and Sunday 14 May there will be some changes to Metrolink services to allow for parts of the work to be completed. Further details will be available on the Metrolink website
nearer the time.
Councillor Andrew Fender, Chair of the Transport for Greater Manchester (TfGM) Committee, said: “As the largest light rail network in the country, there are hundreds of thousands of journeys made and tens of thousands of miles covered on Metrolink each and every week.
“It is therefore absolutely vital that we invest in our infrastructure to ensure we have the necessary capability, resilience and reliability to meet these demands.
“These new substations, along with the other investments being delivered as part of the Metrolink service improvement package, are absolutely vital as the network continues to expand and grow.”
TfGM’s Head of Metrolink, Danny Vaughan, said: “As a result of Metrolink’s recent expansion we’ve seen passenger numbers increase year-on-year, with 37 million journeys made in 2016.
“We will soon be carrying over 40 million passengers annually and providing additional power to the network will help us to sustain that growth.
“I’d like to apologise in advance for any disruption caused during the works and encourage passengers to plan in advance and check before they travel.”
