Between Cardiff Queen Street And Cardiff Bay Stations

Cardiff Queen Street and Cardiff Bay stations are the two termini of the Butetown Branch Line.

These pictures show my trip from Cardiff Queen Street to Cardiff Bay and the trip back.

Note.

  1. Cardiff Bay station is a Grade II* Listed Building.
  2. With passenger usage of nearly a million and a quarter last year, is it the busiest single-platform station in the UK?
  3. It was certainly busy yesterday.
  4. The access for the number of passengers is inadequate.
  5. After removing the foliage, there must be room to add a second track, between the two stations.

This Google Map shows where the railway lines cross.

Note.

  1. Cardiff Central station is to the West.
  2. Cardiff Queen Street station is to the North.
  3. Cardiff Bay station is to the South.

Does the map show that running a service between Cardiff Central and Cardiff Bay stations would be difficult?

Loudon Square Station

The planned Loudon Square Station would appear to be 300-400 metres North of Cardiff Bay station.

Capacity Increase

When the current Class 150 trains with a frequency of five trains per hour are replaced by new Stadler Citylink Metro Vehicles with a frequency of six trains per hour, this will give an approximate doubling of capacity.

And there is always the option of using the Stadler Citylink Metro Vehicles in pairs!

Cardiff Queen Street Station

Cardiff Queen Street station is the first station to be refurbished for the proposed South Wales Metro.

Note.

  1. The station is fully step-free.
  2. The platforms are wide, which helps interchange or waiting for your destination. See Canada Water on the Overground and St. Pancras on Thameslink.
  3. Currently, to get to Cardiff Bay station, you need to catch a five trains per hour (tph) shuttle train from Platform 1.

The service pattern is fairly-straight-forward, with the following lines passing though the station from South to North.

It is said, that to build anything, you need good foundations.

These services through Cardiff Queen Street station, seem to be a good foundation for the South Wales Metro.

The current proposed services through the station after the Metro is completed are.

  • 2 tph – Coryton Line between Penarth and Coryton stations via Cardiff Central – Tri-Mode Stadler Flirts
  • 2 tph – Cynon Line between The Flourish and Aberdare stations.. – Stadler Citylink Metro Vehicles
  • 2 tph – Rhondda Line between Cardiff Queen Street and Treherbert stations – Stadler Citylink Metro Vehicles
  • 2 tph – Rhondda Line between The Flourish and Treherbert stations – Stadler Citylink Metro Vehicles
  • 2 tph – Rhymney Line between Barry Island and Rhymney stations via Cardiff Central – Tri-Mode Stadler Floirts
  • 2 tph – Rhymney Line between Bridgend and Rhymney stations via Cardiff Central – Tri-Mode Stadler Flirts
  • 2 tph – Rhymney Line between Penarth and Caerphilly stations via Cardiff Central – Tri-Mode Stadler Flirts
  • 2 tph – Taff Line between The Flourish and Merthyr Tydfil stations – Stadler Citylink Metro Vehicles
  • 2 tph – Cynon and Taff Lines between Aberdate and Merthyr Tydfil stations via the City Line and Cardiff Central – Stadler Citylink Metro Vehicles.

Summarising services gives these figures.

  • 6 tph – To and from The Flourish – Stadler Citylink Metro Vehicles
  • 10 tph – To and from Cardiff Central – Tri-Mode Stadler Flirts
  • 2 tph – To and from Cardiff Central – Stadler Citylink Metro Vehicles

This Google Map shows Cardiff Queen Street station.

Note.

  1. The bay platform, which is numbered 1, is in the South East corner of the station. is used for services to Cardiff Bay station.
  2. There is no North-facing bay platform.
  3. Northbound trains for Aberdare, Merthyr Tydfil and Treherbert share Platform 5.
  4. Northbound trains for Bargoed, Coryton and Rhymney share Platform 4.
  5. Sounthbound trains use Platforms 2 and 3.

I believe that this layout will be changed  in the creation of the South Wales Metro.

In an ideal world passengers should have a same-platform or cross-platform interchange between services going in the same direction.

If services going in the same direction shared the same platform, this would meet sixteen tph using two platforms, as two tph will terminate at Cardiff Queen Street station.

Canada Water station on the East London Line of the London Underground in a couple of years will be handling twenty tph.

  • The platforms are wide with escalators, lifts and stairs.
  • Four Southern destinations and Two Northern destinations are served.
  • All services are run by Class 378 trains.
  • Access between train and platform is step free and wheel-chairs and buggies can be pushed across.
  • The East London Line has modern signalling.

If Crossrail and Thameslink will be able to handle twenty-four tph with digital signalling, I believe a solution can be found so that sixteen tph can pass through Cardiff Queen Street station.

Having seen wide platforms in operation at stations like Canonbury, London Bridge and Whitechapel, I feel an ideal layout at Queen Street station would be to use Platform 3 for all Southbound services and Platform 4 for all Northbound services, with as  wide a platform as possible in between.

Consider.

  • Passengers from Rymney and Coryton needing to go to The Flourish, would get off the train and get a Citylink for The Flourish.
  • Passengers between The Flourish and Cardiff Central would just have to walk across the platform at Queen Street station to change trains.
  • Passengers needing a train to Rhoose Airport could choose to change at Queen Street station.

Most waits at Queen Street station would be in a few minutes.

Although, passengers would wait longer for Barry Island, Bridgend and Rhoose Airport.

There is still the problem about what to do with the two tph that from Treherbert that terminate at Queen Street station.

  1. They could use Platform 2 or 5.
  2. They could use a new bay platform in the North end of Pltform 3/4.
  3. They could go through Queen Street station to terminate at The Flourish
  4. They could go through Queen Street and Central stations to terminate elsewhere.

Option 1 would have problems.

  • Every thirty minutes a Citylink would have to cross the busy lines to the North of Queen Street station.
  • Passengers wouldn’t always use the same platform for the Rhondda Line.
  • Passengers wouldn’t have an easy interchange at Queen Street station.

Option 2 would be better.

  • The track layout would be similar.
  • Rhondda Line passengers would only have the inconvenience of sometimes walking along the platform.

.Even if this option was not used to turn trains, I suspect it could be built, as it would also be useful for service recovery purposes.

I like Option 3, although it will have the following consequences.

  • ,The Flourish would need to be able to handle eight tph on the two proposed platforms.
  • Queen Street station would need to be able to handle eighteen tph in both directions.

I suspect that both problems are solvable.

The problem with Option 4 is where do you turn the two extra trains?

I suspect that the Citylink vehicles can only use the City Line after Cardiff Central.

Would it be a good idea or not to run four tph on this route?

I don’t know! But a personable young station man at Queen Street station, said that handling the football can be a problem.

So perhaps more trains going to Ninian Park station might be a good idea.

I write about it in detail in The South Wales Metro and Big Events.

Conclusion

Cardiff Queen Street station has the possibility to be a World Class Metro interchange.
