Greater Anglia, The Fen Line And Class 755 Trains

Greater Anglia currently operates two trains per day between King’s Lynn and Liverpool Street stations, in the Morning Peak

  • 05:17 – 07:25 – 2 hr. 8 min.
  • 06:17 – 08:25 – 2 hr. 8 min.

This is matched by three trains a day between Liverpool Street and King’s Lynn, in the Evening Peak.

  • 17:07 – 19:08 – 2 hr. 1 min.
  • 18:-07 – 20:10 – 2 hr. 3 min.
  • 19:07 – 21:05 – 1 hr 58 min.

Note.

  1. The two Morning Peak trains stop at Watlington, Downham Market, Littleport, Ely, Cambridge North, Cambridge, Whittesford Parkway, Audley End, Bishops Stortford and Tottenham Hale.
  2. The three Evening Peak trains call similarly, but miss out Cambridge North.
  3. Services are run by Class 317  or Class 379 trains.

All the passenger trains on the Fen Line including Great Northern’s Class 387 trains, are four x twenty metre cars, which can run as four, eight or twelve cars.

Maximum Length Of Trains On The Fen Line

This article in the Eastern Daily Press is entitled Plans For Longer Trains Between King’s Lynn And London Could Be Delayed.

Reading it, I get the following impressions.

  • The Fen Line can currently accept four-car trains.
  • Eight-car trains are needed.
  • Plans have been or are being developed to lengthen all platforms to accept eight car trains.
  • Network Rail are quoted as saying “The King’s Lynn eight car scheme is amongst the CP5 projects that have funding.”

Extending further might well be out of the question, on grounds of cost and inconvenience to passengers, whilst the work is carried out.

Greater Anglia’s Trains And The Fen Line

There is a problem for Greater Anglia, as both the Class 317 and Class 379 trains are being moved on.

Class 745 Trains

The thirty x four-car Class 379 trains, that work the express West Anglia Main Line services are being replaced with ten x twelve-car Stadler Class 745 trains.

These trains will be too long for the Fen Line.

Class 720 Trains

Five-car Class 720 trains would fit the Fen line and as they are 100 mph trains, like the Class 317 and Class 379 trains, they could handle the current service.

Class 755 Trains

Greater Anglia currently have the equivalent of twenty-eight assorted diesel trains in different lengths, which they are replacing with thirty-eight Class 755 trains.

These are.

  • 100 mph trains.
  • Bi-mode trains with the ability to run on electric or diesel.
  • Compatible with the Class 745 trains.

Fourteen will be three-car trains and twenty-four will be four-car trains.

Greater Anglia, have already said they will run services to and from Liverpool Street from Lowestoft, so will they use the extra trains to run services to and from Liverpool Street to important East Anglian towns?

It is worth looking at the capacity of the various trains.

  • Class 379 train – four-car – 189 2nd/20 1st
  • Class 755 train – three-car  – 166 2nd
  • Class 755 train – four-car  – 224 2nd
  • Class 720 train – five-car – 430 2nd

Would a four-car Class 755 train have sufficient capacity for a service between  Kings Lynn and Liverpool Street?

I think the answer is probably in the affirmative, but a six or seven car train couple be created, by joining two trains together, if required.

So if the Class 755 trains can provide direct Liverpool Street services for Kings Lynn and Lowestoft, what other towns could get a direct service to London?

  • Bury St. Edmunds – Either via Newmarket and Cambridge or Stowmarket and Ipswich
  • Cromer/Sheringham via Norwich and Ipswich
  • Norwich – Via Wymondham, Attleborough, Thetford, Ely and Cambridge
  • Peterborough – March and Cambridge
  • Yarmouth – Via Norwich and either Ipswich or Cambridge.

I can remember, when some of these towns had services to Liverpool Street.

Trains could also split and join at Cambridge and Ipswich to save paths on the main lines to London.

Could trains go up to London in the Morning Peak and return in the Evening Peak?

If there was sufficient demand, they could return in mid-morning and come back to Liverpool Street in mid-afternoon, in time for the Evening Peak.

If so, how many trains would be needed?

  • Bury St. Edmunds (35k) – 1
  • Cromer (7k)/Sheringham (7k) – 1
  • King’s Lynn (43k) – 3
  • Lowestoft (70k) – 1
  • Norwich via Cambridge – 2
  • Peterborough – 1
  • Yarmouth (47k)  – 1

The figures in brackets are the population

Considering, that my rough calculation, showed there were ten spare trains, these numbers seem feasible.

I have some questions.

  • How many Class 755 trains will be able to link together?
  • Will platforms needed to be extended at Liverpool Street
  • Could Lincoln be reached from London, via a reopened March to Spalding Line via Wisbech?
  • Could a Yarmouth and Lowestoft service to London be created by reopening the chord at Reedham?
  • Would it be a good idea to have a dozen First Class seats in the Class 755 trains doing the London commute.

I feel that Greater Anglia have ambitious plans.

Conclusion

From this rather crude analysis, it appears that Greater Anglia will be using the Class 755 trains as three and four car electric trains on the electrified lines to Cambridge, Ipswich and Norwich and then using their diesel power to create new direct routes to the capital.

I also suspect, trains will split and join at Cambridge, Ipswich and Norwich to reduce the number of paths needed to and from London. After all one twelve-car  train is cheaper to run than three four-car trains!

Could Greater Anglia be bringing forward a timetable, where any town in East Anglia, with a population of over say 10,000, gets at least one fast train to London in the morning and back in the evening?

As the tracks, signals and stations are already there, away from the main lines, there may be little that needs doing.

If not, Greater Anglia have bought too many trains.
