Thanks to Twitter follower @ppixx I’ve been pointed in the direction of a FOIA request which resulted in the release of the Working Timetables currently in use (as of 28th August 2016) on Metrolink.

The “Working Timetable” is the hidden “technical” timetable that Metrolink staff use to manage and maintain the service. As such it contains movements of empty trams, like workings to and from depots at the start and end of service. It’s not written to be read by mere mortals.
In terms of what’s happened with our Cross-city Didsbury line commutes, the useful information here is the sequence of trams through the network. This is the bit of information I told you in my last post we didn’t readily have, yet need, to help us make decisions whether to wait for the direct tram or take the first tram and change.
I’ve done the hard work so you don’t have to: What it shows is that if you are travelling to a point beyond Deansgate from the East Didsbury line, during the 6 minute headway period, you may as well almost always wait for the direct tram.
By taking the Deansgate tram and changing, you will have a 4 minute wait for the Altrincham – Bury tram to continue toward Market St, Shudehill and Victoria.
By leaving 6 minutes earlier – because we’re assuming for this example that the first tram is the Deansgate tram – and changing, this is reduced to a 2 minute advantage by the time you get off. The direct tram has almost “caught up”.
However if you are travelling to St Peter’s Square, Piccadilly Gardens or Piccadilly, it makes no significant difference which tram you take from the Didsbury line, both the Deansgate and the Shaw trams have good connections into Piccadilly-bound trams at Deansgate. Both are good options.
