Thanks for this, so, the natural follow on:
- Which lines are which signalling system?
- Is there a list of which trams are TMS-only, which are both systems (as built), and which are both systems (ATS donated from T68s)?
I'm guessing that my local line (Eccles) can be used by any tram, although it appears to be 75% trams number 3080 above.
3119 also in service today, for those interested.
All the new lines opened since 2009 were built with the new system in place (TMS): Media City, Ashton, East Didsbury/ Airport, Oldham Rochdale. The Eccles line was converted from the old line of sight system to TMS in 2010. The city centre was converted in 2012.
Conversion is still on going on the Alrincham and Bury lines with Cornbrook to Brooklands on the Altrincham Line being converted in (i think) 2013. On the Bury line, Victoria to Crumpsal was converted (I think) in 2015.
The remaining areas under the old system are therefore Crumpsall to Bury and Timperley to Altrincham. Crumpsal to Bury is straighforward and should be converted I believe around the time the second city crossing opens (this is delayed from July this year due to issues with the TMS system at Victoria which need to be resolved for the second city line to open).
On the Altrincham line it is a bit more complex as the section between Timperley and Altrincham is owned and controlled by Network Rail. This section is controlled by an old fashioned signal box and there are two level crossings with gates. But network rail will migrate the signalling in this area to the new Ashburies signalling centre in a few years so it obviously doesn't make any sense to design a highly complex interface between systems which will only be needed for a few years.
Instead only the TMS components needed to track trams and supply data to the customer information screens will be installed and this is expected to be activated very soon (within a few weeks). This area will be under signal control for the foreseeable future.
According to British Trams Online:
3001-3060 are fitted with ATS and VRS and can be used anywhere on the Metrolink network. These units are split between Queens Road and Trafford depots.
3061-3118 are not fitted with ATS/VRS equipment and can only be used on services to Ashton-under-Lyne, East Didsbury, Manchester Airport and Rochdale. These units are now split between Trafford and Queens Road depots.
I don't think the units in the factory installed TMS fleets vs salvaged TMS subfleets is published anywhere. Once the Bury line is converted I would expect that the equipment needed to work on the old signalling system will be removed from all but a few trams to save on maintenance costs. Maybe it will be stored and not disposed of in case it is needed in future.
Any tram in the fleet can use the Eccles Line but normally Eccles trams come from the Trafford Depot. Each tram has a home depot. That is why you only see certain numbers on certain lines.
