The Anonymous Widower

What Will Happen To The Class 319, Class 455, Class 321 And Cl;ass 317 Trains?

When I go to Walthamstow to have supper with my son, I regularly travel from Hackney Downs station in one of London Overground’s Class 317 trains.

For a metro train, some are unusual in that they still have the First Class compartment and spacious 2 + 2 seating in the rest of the train. Also, as some at one time used to work the Stansted Express service, they have multi-lingual safety instructions and luggage racks.

Like the Class 319, Class 321 and Class 455 trains, they are going to be replaced by new trains by their current operators.

So what will happen to the various trains.

The Class 319 Flex Train

Porterbrook, the ROSCO, who own the Class 319 and Class 455 trains have developed the Flex concept that can transform these classes into much-needed four-car bi-mode trains. We should be seeing Class 319 Flex trains under test by the end of the year.

As the Class 319 Flex train has now been given its own TOPS-number of 769, the powers-that-be must think it is a viable concept.

In Metro Development With Flex Trains, I describe how I believe Northern are going to use the Class 319 Flex trains in the North West in the Liverpool, Manchester and Preston triangle, to develop a world-class Metro network.

The Class 455 Flex Train

The applications of a Class 455 Flex train would probably be less than that of a Class 319 Flex train, as the trains are 75 mph third rail trains, as opposed to 100 mph dual-voltage units.

The Class 319 and its Flex version will travel on say the West Coast Main Line with ease, but the slower Class 455 train would be a rolling roadblock.

But because they have a high-quality 2 + 2 interior, they could find applications as much-needed four-car diesel multiple units.

The interiors are certainly some of the best on short distance suburban trains and I would rate them better than some stock delivered in the lst couple of years.

The Class 455 Flex Train And Pacer Replacement

Class 455 Flex trains would make a superb replacement for the dreaded Pacers.

  • Class 455 trains were built to withstand the impact of a 24-tonne cement mixer truck falling from the sky. Try repeating the Oxshott accident with a Pacer.
  • The Class 455 interior is comfortable and South Western Railway‘s fleet was fully refurbished around 2003.
  • The Class 455 Flex train will have at least the performance of a Pacer.
  • The Class 455 trains meet all the latest Rail Vehicle Accessibility Regulations.
  • Could the Class 455 Flex train be given the same hill-climbing capability of a Class 319 Flex train?
  • The Class 455 train is four-cars as opposed to the two-cars of a Pacer.

Ironically, the Pacers are a few years younger than the Class 455 trains. But then class is permanent! Or should that be Mark 3 coaches are permanent?

I think that Porterbrook are looking at converting the Class 455 trains for several reasons.

  • They own ninety-one Class 455 trains, that will be released by South Western Railway.
  • The quality interiors probably just need good cleaning and cosmetic repairs.
  • The costs and rate of conversion are now well-known.
  • The Pacers need to be replaced quickly.

It should be noted that the number of Pacers in service are as follows.

  • Class 142 – Arriva Trains Wales – 15
  • Class 142 – Northern – 79
  • Class 143 – Arriva Trains Wales – 15
  • Cl;ass 143 – Great Western Railway – 8
  • Class 144 – Northern – 23

The only replacements on order are Northern’s 25 x two-car and 30 x three-car Class 195 trains.

That means that 140 two-car Pacers are being replaced by the same number of vehicles.

So there is a short term need for some quality trains. If all the Cl;ass 455 trains were converted that would add another ninety-one quality trains that could be used to replace Pacers.

The Welsh and Great Western Pacers are used far from any 25 KVAC electrification, so the inability to use electrification on a Class 455 Flex will be irrelevant. But both Wales and the West Country have lines with challenging gradients.

So if the Class 455 Flex train was designed to be able to handle the Manchester to Buxton test route, the trains could handle the Cardiff Valley Lines and the challenging lines in Devon.

Currently, the Class 455 trains have a very red interior, which would surely go down well in the Principality.

The 100 mph Bi-Mode Train

The rumoured large response to Porterbrook’s proposal for the 100 mph four-car bi-mode Class 319 Flex train, says to me, that there is a market for a train, with the following characteristics.

  • 100 mph operating speed on electricity.
  • Over 90 mph operating speed on diesel power.
  • Four-car

Both the Class 321 and Class 317 trains could be modified to fit this specification.

Class 321 Flex Trains

Greater Anglia have around a hundred of these trains, which will be replaced by brand-new Aventras in the next couple of years.

  • They were built in the late 1980s.
  • They have a 2 + 3 interior.
  • Class 321 trains can be modified for dual voltage.
  • Thirty are being upgraded under the Renatus project, which involves new air conditioning and heating, seating and Wi-Fi.
  • A new traction package with new AC traction motors and regenerative braking has been designed.
  • They are owned by Eversholt Rail Group.
  • The trains are probably very similar electrically to the Class 319 trains,

If needed, there must be scope to convert some of these trains to bi-mode using similar engineering to the Class 319 Flex trains.

I haven’t ridden in a Class 321 Renatus, but pictures on the web, indicate the train could have a high-class interior.

It would appear that with the Renatus treatment, the Class 321 trains could be transformed into a high class train.

The market would decide, if some were converted into bi-mode Flex variants.

Class 317 Flex Trains

Greater Anglia and London Overground have around seventy of these trains, which will be replaced by brand-new Aventras in the next couple of years.

  • They were built in the early 1980s.
  • They have a 2 + 2 interior, to a variety of standards, but mostly in generally good condition.
  • Some have First Class compartments.
  • Some were built for the Stansted Express and have luggage racks.
  • All are 25 KVAC units.
  • They are owned by Angel Trains.
  • Plans exist for the fitting of a new traction package if required.

As with the Class 321 trains, there must be scope to convert some of these trains to bi-mode using similar engineering to the Class 319 Flex trains.

The Future

The four main train types , that I have have listed are all slightly different.

  • Class 317 is a 100 mph, 25 KVAC overhead only, good 2 + 2 interior
  • Class 319 is a 100 mph, dual-voltage train, average 2 + 3 interior
  • Class 321 is a 100 mph, dual-voltage train, average 2 + 3 interior
  • Class 455 is a 75 mph, 750 VDC third-rail only, good 2 + 2 interior

There are also smaller numbers of other types that could also be converted.

Different train types will be better suited to different markets.

I’ll list some of the markets in the next few sections.

Route Extensions

This is probably the simplest application of a Flex train.

Consider the new Bromsgrove station at the Western end of the Cross-City Line in Birmingham.

From May 2018, the station will have been electrified and new electrified services will start across Birmingham from Bromsgrove.

West from Bromsgrove it is under twenty miles to Worcester, which is getting a new station at Worcestershire Parkway.

Bromsgrove to Worcestershire Parkway would be well within range of a Flex train.

How many simple extensions to electric services could be created with a few Flex trains?

There could be quite a few and some might even be extensions to third-rail networks using Class 455 Flex trains.

Metro Development

In Metro Development With Flex Trains, I discuss how Northern are developing the Northern Electric network in the Liverpool, Manchester and Preston triangle, using a mixed fleet of electric and bi-mode Flex version of the Class 319 trains.

Various places in the UK have plans for Metros and where there is some electrification a mixed fleet of electric and bi-mode trains could be used to develop the metro.

The mixed fleet of electric and bi-mode Flex trains gives the train operator advantages.

  • Passengers have a similar customer experience across the fleet.
  • The Flex trains can go anywhere on the network.
  • The electric trains can only work electrified lines, but as more electrification is added, they can take advantage.
  • Flex trains can deputise for electric ones.
  • If there is a problem with the electrification, the Flex trains can still get through.
  • Drivers and other staff don’t have two very dissimilar train types to deal with.
  • Maintenance must be simplified.

I feel that Class 319, Class 321 and Class 317 trains could all be offered in both electric and bi-mode Flex versions.

Several of the possible places where a Metro needs to be developed like Hull, Leeds, Middlesbrough, Newcastle, Sheffield and Stoke-on-Trent are in Northern territory, so for preference, Northern would probably use Class 319 trains, especially as they have the ability to cruise safely at near 100 mph on the West and East Coast Main Lines.

But there is only so many Class 319 trains, so I suspect Northern will have to look at other types.

A city that could benefit from the Flex approach is Leeds.

  • There is a mix of electrified and non-electrified local lines from Leeds station.
  • Some important local routes like Leeds to York and Sheffield are not fully electrified, but could be worked by a Flex train.
  • Northern use five Class 322 trains in the Leeds area. These are very similar to Class 321 trains.
  • Northern need some more stock for the electrified lines from the City and have brought in some Class 321 trains.
  • Leeds station seems to me to have a platform capacity problem.

I feel that a few Class 321 Flex trains and some reorganisation of services so some ran back-to-back through Leeds station could be beneficial.

One point about a mixed fleet of electric and bi-mode Flex trains must be raised.

Suppose an operator is thinking of using a mixed fleet to create a local Metro around a City and that calculations say that to work the required service would need six electric and four bi-mode trains.

Would the operator perhaps buy five trains of each type and use one bi-mode as an electric train most of the time?

But surely, this would be inefficient as the bi-mode would be dragging its diesel power packs around all day.

But the bi-mode trains have an advantage, in that they can still operate if the electrification has failed.

They might also be able to rescue a stalled train and drag it back to the depot.

Diesel Multiple Unit And Pacer Replacement

The Rail Vehicle Accessibility Regulations are going to kill off a lot of diesel multiple units and especially the Pacers.

Operators with Pacers are going to need to act quickly and as I showed earlier in The Class 455 Flex Train And Pacer Replacement, a  Class 455 Flex train would be a very able replacement.

  • Similar performance.
  • Four cars instead of two.
  • The unmatched ride of the Mark 3 coach.
  • Modern, comfortable high-quality interior.
  • Full compliance with the accessibility regulations.

For operators with lots of Class 150 and Class 156 trains, which need to be refurbished, a Class 455 Flex train would be a very able deputy.

In some places, where two Class 150 trains work as a pair, replacing them with a single Class 455 Flex train, may give operational and capacity advantages.

The High Speed Parcel or Pallet Train

In The Go-Anywhere Express Parcel And Pallet Carrier, I proposed using Class 321 trains as HSPTs of High Speed Parcel or Pallet Trains. In the manner of all Mark 3-based trains, they would undoubtedly make an excellent fist of this job.

Both electric and bi-mode Flex versions could be used to give a go-anywhere fleet.

I suggested using Class 321 trains, as some of them have very basic interiors, so conversion would be less costly to parcel carriers than acceptable passenger trains.

Conclusion

The train refurbishing companies are going to be busy.

The real beauty of this approach, is that what trains get created will depend on what is needed and how much train operators are prepared to pay.

But there are also plenty of trains for most applications.

Cats are supposed to have nine lives, but that is nothing compared to a Mark 3 coach.
