Mathematics Of A Stadler Flirt Akku Battery Train

In Stadler Receives First Flirt Akku Battery Train Order, I  quoted thia from as that of this article in Railway Gazette International.

Schleswig-Holstein transport authority NAH.SH has selected Stadler to supply 55 Flirt Akku battery multiple-units to operate regional services and provide 30 years of maintenance.

This is a substantial order for a large number of trains and many years of maintenance, and would appear to be structured similarly to deals in East Anglia, Glasgow and Liverpool in the UK.

Does The Train Have A Central Power-Pack Car?

Is the Flirt Akku, similar to Greater Anglia’s Class 755 trains and other of the companies products, in that it has a central power-pack car?

This picture shows a Class 755 train at Norwich.

 

Note that this four-car train has four full-size cars and a shorter one, that doesn’t appear to have any doors or proper windows.

This is the power-pack car, which in these trains has the pollowing properties.

  • The power-pack car is 6.69 metres long.
  • The power-pack car is identical in both the four-car and three-car versions of the Class 755 trains.
  • The four-car trains have four diesel engines.
  • The three-car trains have two diesel engines.

The number of engines possible, leads me to believe there are four slots for engines in the power-pack car.

Transport for Wales have ordered a number of Flirts, which are similar to those in use by Greater Anglia, but they are tri-mode trains, that can run on overhead 25 KVAC electrification, diesel or battery power.

I speculate that they have one diesel engine and three batteries in the four slots.

This is a picture of the Flirt Akku.

I have enlarged the image and it would appear that the trains do not have a central power-pack car, but they do seem to have a lot of electrical gubbins on the roof.

This video shows the Class 755 train being tested at Diss.

It looks to have a much smoother roof line.

Could this indicate that the batteries on the Akku are placed on the roof of the train, as there is certainly a lot of equipment up there?

Eviation Alice Illustrates The Choice Of A Good Name

I have set up a Google Alert for Eviation Alice and it is finding a lot of articles.

It not only illustrates that the arrival of an electric airliner excites people, but also that the choice of name is a good one.

I Have Just Setup My July Tax Payment

I received my Self Assessment Statement yesterday and have just setup the payment on-line.

My father didn’t do any Government printing, as he said, that they always wanted very small type and at fifty, his eyes weren’t up to it.

I find in checking the account to pay the money, that the form is still confusing and I need to get my magnifying glass out.

  • There would also appear nowhere to print a large format version of the instructions.
  • Or details in another language for that matter!
  • There is a help web-address at the bottom. In very small type. It should be in an easy-read twelve point type.

HMRC can do better!

But they don’t care, as if you put in the wrong amount, it’s your fault not theirs.
