The Design Of The New Greater Anglia Class 745 Train

I am writing this article about the new Class 745 trains for Greater Anglia, as I think they fit the evolving pattern of train design.

The Article In The July 2017 Edition Of Modern Railways

In the July 2017 Edition of Modern Railways, there is an article entitled GA Shows Off Stadler Mock-Up, where this is said.

GA’s fleet will all offer air-conditioning, wi-fi, plug and USB points, electronic seat reservations and will have a low floor design to offer improved accessibility.

I would expect no less!

This is also said.

The 12-car EMUs are formed of two six-car sets permanently married together. Each six-car set has one power bogie at each end, with a total of four on a 12-car train.

As the train has a First Class section and the bistro buffet between First and Second Classes, I suspect there could be two different types of six-car set.

  • One with the First Class seats, the bistro buffet and perhaps a couple of Second Class cars.
  • One with Second Class seats.

Normally, trains will be formed of one of each set.

I would assume, if say two six-car sets were out of service for some reason, the two working sets could be married to create some temporary capacity.

But yet again we see a train and a half-train philosophy.

Bicycle Spaces

As the Norwich trains will have six bicycle spaces, perhaps three will be placed in each set.

The article also says that Stansted Expresses will have eighteen spaces. Perhaps, Class 745 trains have a movable bulkhead at the end opposite to the cab, so that bicycle capacity can be tailored to the expected passengers.

Surely, being able to book your bicycle on the train going to East Anglia for the weekend will not be a feature that is not used.

Capacity To Norwich

Currently, there is two trains per hour (tph) between London and Norwich via Colchester and Ipswich, which are eight-cars long.

The new trains will enable 3 tph, each of twelve-cars, which is more than doubling the number of cars in an hour.

Train Power

The current Class 90 locomotives have a power output of 930 kW to pull the eight coaches.

It could be that each of the four powered bogies are rated at 1000 kW, so if that is right, these new trains are much more powerful than the current ones.

This is an extract from the article.

GA is currently investigating the potential to change from diesel to electric power on the move, and says it will seek to utilise the environmental benefits of electric power wherever possible, even on short stretches out of Norwich and Ipswich stations.

All units are designed for 100 mph operation, but with the potential for upgrading to 110 mph in future.

Does the speed upgrade apply to both the electric and bi-mode units?

Knowing the lines well, I suspect that the extra speed could be useful on the following lines.

  • Stowmarket to Norwich
  • Cambridge to Norwich

I suspect that if there is more improved double-track introduced, there couple be other places.

Conclusion

So expect Norwich-in-Ninety and Ipswich-in-Sixty!
