The Anonymous Widower

Werrington Dive-Under – 8th September 2021

I had gone to Peterborough to take pictures of the Werrington Dive Under, from a train between Peterborough and Spalding.

I took these pictures going Peterborough and Spalding.

My train between Peterborough and Spalding stations took the following route.

  • The Class 158 train was a great improvement on the Class 153 train, I took in From Peterborough To Lincoln in 2015.
  • It started in Platform 1b at Peterborough station.
  • It then crossed over to the Down Fast line to go North.
  • Finally, it slowed to cross the Up Fast and Up Slow lines to go towards Spalding.
  • It is surely not an efficient and the safest way to run a railway.

Think about turning right on a busy dual carriageway, by going through a gap in the central reservation.

This diagram shows the new track layout of Werrington Junction.

Note.

  1. My train was going North on Line 5, so it had to use the two crossovers to get to the lines to Spalding.
  2. The Up Stamford (Line 4) can be seen in the pictures after the two lines have disappeared into the dive-under.

It’s a pity the first of my pictures aren’t better, but the sun was in the wrong direction.

I took these pictures going Spalding and Peterborough.

Note.

  1. The train used the Up Slow (line 7) to go between Werrington Junction and Peterborough station.
  2. The last two pictures show the Class 158 train in Platform 1b at Peterborough station.

At least this time, the train didn’t cross the Fast lines.

Will Passenger Trains Use The Werrington Dive-Under?

I’m very sure they will!

  • On the Western side of Peterborough station, there are four platforms 4 to 7 and an avoiding line for freight trains going North.
  • It appears that all of these lines can access the Down Stamford (Line 1) and Up Stamford (Line 4) to go to Werrington Junction.
  • At Werrington Junction, trains either take the route to Stamford or use the dive-under for Spalding.

It looks to me, that if the trains to and from Spalding terminated in one of the Western platforms, then they could use the Stamford Lines to access the dive-under and they wouldn’t cross the Fast Lines of the East Coast Main Line on the flat.

Greengauge 21’s Suggestion, That Thameslink Be Extended To Spalding

In the study by Greengauge 21, which is entitled Connecting East Lincolnshire, this is said.

As noted the Spalding-Peterborough line should be a strong candidate for electrification because of its freight potential, and if so it could also accommodate an extension of Thameslink services from London and the South East to Spalding where interchange would be made with a Spalding–Boston–Louth–Grimsby express bus using the A16.

This proposal may be possible, if instead of using the dive-under, the Thameslink trains were able to use the Up Slow (line 7) to go both ways between Werrington Junction and Peterborough station.

As in the near future, full digital signalling will apply through Peterborough, this shouldn’t be a problem.

Electrification Of The Werrington Dive-Under?

Consider.

  • There is a gap of around ninety miles in the freight route between the comprehensive electrification at Peterborough and Doncaster stations on the Great Northern and Great Eastern Joint Line (GNGE).
  • There are dozens of level crossings.
  • The route goes through the centre of Lincoln, where there are two level crossings.

There are two ways of decarbonising the route.

  • Full electrification
  • Using hydrogen-powered freight locomotives.

Both solutions have their proposers and opponents.

I favour hydrogen-electric hybrid locomotives, that can use electrification where it exists, as it reduces the infrastructure cost on overbridges and in freight depots.

  • Hydrogen-powered locomotives have a go-anywhere capability.
  • There are also a lot of routes in the UK, where freight trains currently run and it would take a long time to electrify all of them.
  • As rail freight companies would have to purchase a lot of new locomotives, I can see them opting for hydrogen-electric hybrid locomotives.

But there are others, who think the only way is full electrification.

London And Lincolnshire By Electric Train

Passenger trains are not a problem, as Alstom, CAF, Hitachi, Stadler and others have demonstrated battery ranges of over fifty miles.

LNER are currently serving Lincoln from London using Hitachi bi-mode Class 800 trains, which use diesel for the 16.5 miles between Newark and Lincoln.

Hitachi’s proposed Intercity Tri-Mode Battery Train, is described in this Hitachi infographic.

I believe it would be possible to handle London and Lincoln via Newark without using diesel.

It also looks like it will be possible to convert the LNER’s current Class 800 trains into Intercity Tri-Mode Battery Trains.

But I doubt their range would sufficient to go between London and Lincoln via Peterborough, Spalding and Sleaford, unless there were to be a charging system at Lincoln.

But surely though, the ideal train for Lincolnshire would be a train that ran between London and Cleethorpes via Peterborough, Spalding, Sleaford, Lincoln, Market Rasen and Grimsby Town.

  • Peterborough and Lincoln is 56.9 miles.
  • Lincoln and Cleethorpes is 47.2 miles.
  • The service could be timed for a convenient interchange with the other Lincolnshire train services.
  • The service could run perhaps a few times per day.

With charging systems at Lincoln and Cleethorpes, similar to the Hitachi ABB Power Grids system that I described in Solving The Electrification Conundrum, this service could be run by an Intercity Tri-Mode Battery Train.

Peterborough And Lincolnshire By Electric Train

If you could run between Peterborough and major places in Lincolnshire, as part of a London service, I also suspect that a well-designed Peterborough and Lincolnshire service could serve Lincolnshire almost equally well.

It might use Platform 5 to terminate at Peterborough.

  • This is paired with Platform 4, which is the platform generally used by LNER trains from London, so there would be a cross-platform interchange going North.
  • Going South, there would be a need to use the footbridge.

How many people would use an hourly cross-TransLincs service?
