The Anonymous Widower

Where Will Greater Anglia Deploy The First Class 745 Trains?

This article on Railway Gazette is entitled ‘Gorgeous Beast’ Will Change Perception Of Rail Travel.

This is unusual language, when you’re talking about modern diesel and electric trains, especially when it comes from the CEO of a financial company investing in trains, as a safe long-term investment for money like pension funds.

But if the Class 755 trains cause Mark Swindell to use such language, they must have something about them.

Perhaps, it’s the fact that they follow the layout of the legendary and much-loved by some, Class 442 train, which also had a power-car in the middle. It is informative to compare the Class 442 train with a four-car Class 755/4 train.

  • The 442’s power-car is electric, whilst the 755/4’s is diesel/electric and can be diesel/electric/battery.
  • The 442 has seats for 346 in two classes, whilst the 755/4 has 229 in a single class.
  • The 442 has 1200 kW of power, whilst the 755/4 has 2600 kW on electric power and 1920 kW on diesel-electric power
  • Both are 100 mph trains, although the 442 holds the World Record for a third-rail train at 108 mph.

I am drawn to the following conclusions about the Class 755 train.

Passenger Comfort

Passengers will have plenty of space, in addition to the customer comforts, which appear to be of a high standard.

Some passengers might miss First Class, but will the extra space compensate.

Power

The power figures quoted in the Railway Gazette show the following.

  • In electric mode, the train will have more than double of the power of the 442.
  • In diesel-electric mode, the train has sixty percent more power, than the 442.

This will mean that the train should have superb acceleration.

Top Speed

With all this power, the planned operating speed of 100 mph will be determined more by the track, signalling and other trains, rather than any limitations of the trains.

There are three improvements in Network Rail’s Improvement Pipeline, that will allow faster running by Class 755 trains.

  • Trowse Swingbridge
  • Haughley Junction doubling
  • Ely Area service improvements

The improvement will help these services by Class 755 trains.

  • Norwich to Stansted Airport via Ely, Cambridge North and Cambridge.
  • Peterborough to Colchester via Ely, Bury St. Edmunds and Ipswich
  • Cambridge to Ipswich

I could also see the operating speed on the Breckland Line raised.

Routes

How will the routes be affected by trains with a better performance?

Norwich To Stansted

Currently, the two legs take.

  • Norwich to Cambridge – 1:24
  • Cambridge to Stansted – 0:39

Which adds up to a convenient 2:03.

With the faster trains and eight stops, it looks like this route could be done several minutes under two hours, with a round trip of four hours, which would need four trains for a one train per hour (tph)service.

Ipswich to Cambridge

Currently, this route takes 1:16 with eight stops.

This is not very convenient and the time savings needed to get the route under an hour will not be easy.

Colchester to Peterborough

Currently, the two legs take.

  • Colchester to Ipswich – 0:19
  • Ipswich to Peterborough – 1.41

Which adds up to a convenient 2:00.

With the faster trains, it looks like this route could be done several minutes under two hours, with a round trip of four hours, which would need four trains for a one tph service.

Ipswich to Lowestoft

Currently, this route takes 1:26 with nine stops.

With the faster trains, it looks like this route could be done several minutes under one-and-a-half hours, with a round trip of three hours, which would need three trains for a one tph service.

It also looks like up to three trains per day will run from London to Lowestoft.

So Which Route Will Get The New Trains First?

Greater Anglia will obviously deploy them, where there is the greatest need for extra capacity or there is the greatest return to be made!

I think, we’ll see them on the Lowestoft route or between Cambride and Norwich first.

They’ll certainly be worth waiting for, if Mark Swindell is right.
