From the start of service on Monday 12 February, the East Didsbury-Shaw and Crompton service will operate between East Didsbury and Exchange Square only. There will be no peak service between Shaw and Crompton and Exchange Square.
The East Didsbury-Rochdale Town Centre service will continue to operate via Market Street, Shudehill and Victoria, and there will be additional double trams so everyone can make their journey.
This change has been made to reduce congestion in Manchester city centre, journey times and the number of delays across the Metrolink network since the broken rail at Victoria has seen 8 trams every 12 mins using Mosley St in each direction.

That seems to be a good temporary plan. There is a loss of frequency but same capacity with all stops open.
