The Anonymous Widower

What Is It With The Welsh And Batteries?

If ordering two fleets of rail vehicles with batteries, that I wrote about in The Greening Of The Valleys, KeolisAmey Wales have now gone and ordered a third fleet for North Wales.

This article in the Railway Gazette is entitled Vivarail D-Trains For Wales & Borders.

This is the first paragraph.

Incoming Wales & Borders franchisee KeolisAmey is to take delivery of five three-car Class 230 D-Train diesel-battery multiple-units from Vivarail, which is to produce them using the bogies and aluminium bodyshells of withdrawn London Underground D78 metro trains.

Note that they are described as diesel-battery trains.

The article says the Class 230 trains will be used on these lines.

Five trains have been ordered, but I suspect it will eventually be more.

I believe that this picture shows a property of the Class 230 train, that would be ideal for Welsh routes or any other scenic lines.

They have large windows and get the interior design right and they could become an iconic way to fill a difficult niche market.

  • A reliable hourly or half-hourly service on a remote line.
  • A quality interior with everything customers expect like a fully-accessible toilet, wi-fi and power sockets.
  • Space for bikes, buggies, babies and wheel-chairs.
  • Step-free entry between train and platform was possible at some stations on the District Line and I suspect that many stations could be made, so that wheelchairs and buggies could just roll across.
  • The ability to be serviced remotely.

Note that the train is fitted with toilets from Cwmbran in South Wales.

Did Transport for Wales say, that if you fitted Welsh toilets, we’ll buy a few trains?

I suspect though, that they are much better toilets, than those I saw as a child in castles like Caernarfon, Conway and Harlech, where the inhabitants in the Middle Ages must have been quick on the job to avoid the getting shot with arrows, where it would hurt!

I suspect constipation was rare in those days!

Seriously though, here’s a video of the Class 230 trains for Wales.

This video comes from this article in this article on

How Do The Trains Work?

I obviously don’t know exactly, but I suspect the method of operation is very similar to that of some of the advanced hybrid buses, like a new Routemaster.

Each of the diesel engines have a generator, which produces electricity. This can either be fed directly to the traction motors to power the train or stored in the onboard battery.

The train’s control system manages the power and chooses, whether traction power comes from the diesel engine or the battery.

This means that the diesel engines don’t have to work all the time.
