Additional Double Track In South Wales

In the July 2018 Edition of Modern Railways, there is an article entitled KeolisAmey Wins Welsh Franchise.

This is said about the additional double track on the South Wales Metro.

Additional double track will be needed in 15 locations to support increased Core Valley Lines (CVL) frequencies.

So where are these locations?

I shall start by listing all the single platform stations.

I have ignored the following.

  • Terminal stations.
  • Stations on the Coryton Line.

I have grouped them by branch.

Aberdare Branch

Merthyr Branch

Rhondda Line

Rhymney Line

These total up to fourteen stations.

As the Butetown Branch will be extended through Cardiff Bay station and this station will need a second platform, does this add up to the fifteen new sections of double-track?

How Difficult Will It Be To Add A Second Track At Stations?

Of the fifteen stations, those on the Aberdate, Merthyr and Rhondda will only see the Stadler Citylink Metro vehicles, which will be running to the same rules as trams.

So could it be that these stations will be arranged like this stop on the London Tramlink, which is typical of many tram stops throughout the UK, Europe and the world?

Note.

  • There is no bridge.
  • There is full step-free access.
  • The overhead wires are kept well out of thew way.

As most tram networks have done in the UK, they could design a modern suite of shelters, ticket machines, information displays, seats help points and other items.

I suspect that the platform height would be designed to fit both the tri-mode Stadler Flirts and the Stadler Citylink Metro Vehicles.

The only stations that are served exclusively by the tri-mode Stadler Flirts and might be given an extra track are Pontlottyn and Brithdir stations at the Northern end of the Rhymney Line.

These stations only get four tph in both directions.

Do Many Stations Have Passing Freight Trains?

I never like to be on a platform, when a freight train goes through and it happens regularly at stations near me like Canonbury and Dalston Kingsland.

I looked on Real Time Trains and there don’t appear to be many such trains on the CVL

I suspect too, that they could use temporal separation, with any freight trains ruining, when the Metro is closed.

Conclusion

I do find it strange that the total number of one platform stations is the same as the number of locations, where the track will be doubled.

But surely, if all stations were on a double-track, this would give the maximum flexibility to run services.

If too, the stations could be built without footbridges to the standards of trams, then construction costs could be saved!
