Should The Valley Lines Be Electrified?
I travelled about thirty percent, if that, of the Valley Lines that fan out from Cardiff. But it gave me a feeling of the strengths and weaknesses of the lines.
Stations
A Strength
If I compare the stations I saw on the Valley Lines most would score better than the average of those on the Lea Valley Lines, being taken over by the London Overground. The platforms seemed in good condition and most stations had some form of shelter, which was often new. They certainly didn’t have the same sense of abandonment of some stations on the Lea Valley Lines.
Platforms in some stations might also be big enough for a small kiosk. Obviously, coffee outlets work in London and probably Cardiff, but would they work in the valleys?
On the subject of stations, I hadn’t expected to find a ten million pound project at Pontypridd.
Footbridges
A Possible Weakness
I didn’t see any truly dangerous footbridges, that are very much the norm on the Lea Valley Lines, so hopefully they are not as common.
But some footbridges like Taff’s Well may well have to raised for electrification.
Step Free Access
A Possible Weakness
According to a Network Rail document on the Internet, several stations will have improved access.
On point on step-free access and lifts, is that Network Rail are installing this across the network and I have a feeling that they’re getting better at doing it, as some of the schemes in London, seem to have gone in extremely fast. Perhaps, their project management is getting better.
Road Bridges
A Strength
Network Rail’s documents don’t seem to mention any bridges being reconstructed.
An aside here, is that they are putting in extra tracks in places and this is mentioned.
So perhaps there isn’t work to do with the bridges to accommodate the overhead wires.
Signalling
A Strength
This looks like a separate project to the electrification, as unlike in many places you can do the signalling first and then electrify.
It’s all described in this Network Rail web page.
In one way, the signalling will give more train paths and capacity, before the electrification is complete. But where do you get the required diesel trains?
Interchanges
A Strength
I only did a couple of simple journeys on the Valley Lines, but like the East London Line, you can do same or cross platform changes in a lot of places.
Current Trains
A Weakness
The Class 142 trains that work the lines are clapped and in a few years time, they’ll have to be withdrawn because of the disability regulations.
The Class 150 trains may be possible to be updated, as some Class 153 have been. But would that be throwing good money after bad?
New Trains
A Weakness Or A Strength
New trains are expensive and these Valley Lines could require quiet a few sets.
But there are Class 315 and Class 317 trains available for cascade, as new trains arrive on Thameslink. Crossrail and the Overground in London in the next few years.
The Class 315s are nearly forty years old, but were refurbished between 2204 and 2008. In a section on their future Wikipedia says this.
As most duties of the 315s will be taken over by new Class 345 Aventra trains once Crossrail is built, it has been suggested that the 315s could be cascaded to Wales to be used on Valley Lines services in the Cardiff area following electrification.
I travel regularly on Class 315s and they certainly are a better ride than a Class 142. Their problems are the awful pink décor, dirty windows and lack of a passenger information system. Some might find the lack of toilets a problem too!
Information systems are apparently being fitted, but obviously not on the ones I’ve used and the dirty windows doesn’t seem to be a problem that affects Welsh trains, like it does Greater Anglia. They are all four car sets, which can be paired to make 8 car trains with seats for over 600.
The Class 317s are the electric cousins of the Class 150s operating on the Valley Lines now, are not quite as old as the Class 315s and some of them were refurbished to a high-standard in the 1990s. I used to travel on the latter regularly into London from Suffolk, and they’re certainly better than the 315s. They could also be fitted with better electrical equipment. A demonstrator is currently running round East London and Essex. South West Trains have recently refurbished their Class 455s, which are their version of the 317.
You have to remember that underneath the awful paint jobs and bad interior design of Class 317 and Class 455 trains is a legendary 100 mph Mark 3 carriage, which is struggling to get out. South West Trains have shown what is possible.
I suspect as there are large numbers of both classes, some will end up on the Valley Lines. I’d put my money on Class 317s as their 100 mph capability gives them the ability to run longer-distance stopping services on main lines.
Power Supply
A Strength
One of the high cost parts of railway electrification is getting the electrical feed to the the overhead lines. And our piecemeal policy of the last few decades has made things worse, as you can’t do clever and sensible things to make things simpler and cheaper. For example, the Great Western Main Line electrification, will not have its own power supply at the London end, but will share one with Crossrail.
So as the South Wales Main Line will be electrified all the way to Swansea, it should be possible to feed the Valley Lines off the infrastructure installed on the main line.
Conclusion
As I travelled around the Valley Lines yesterday, several railway staff were sceptical that electrification will go ahead.
I may be wrong, but it seems to me that if after the Great Western Main Line is electrified in 2017, it would actually be more expensive to not do the Valley Lines electrification, as you’d still have the problem of the trains and you’d have a series of lines with good stations, ready to electrify.
It does seem to me, that Network Rail have done their project management superbly well on the updating of the Valley Lines.
I have this feeling, that the scheme when completed will be a big success, as the Valley Lines have so much going for them in terms of location.
The more I look at the Great Western and its branches in Wales and the West Country, I just can’t understand, why these schemes we are doing now, weren’t carried out decades ago.
There are an awful lot of politicians of all parties, who should hang their heads in shame.
