300th Coradia Polyvalent Train Delivered By Alstom

The title of this post is the same as rgar of this article on Rail Advent.

The Polyvalent is a variety of the Alston Coradia, that was first ordered for France.

This is the description of the train in Wikipedia.

As of 2018, the Coradia Polyvalent is the latest variant in the Coradia family. It can operated at a maximum speed of 160 km/h in electric or bi-mode at voltages of 25 kV and 1,500 kV; a cross-border version capable of operating at a voltage of 15 kV, suitable for the German and Swiss rail networks, has also been made available. The low integrated floor of the carriages provides improved accessibility and a high level of visibility to passengers. As a measure to restrict vibrations and noise levels, motorised bogies are placed at both ends of each carriage.

The Rail Advent article adds this.

In response to the hydrogen plan by the French Minister, Alstom is now looking to incorporate a dual-mode hydrogen version of the Coradia Polyvalent range.

I would assume, this means an electric train, that can use hydrogen power, when the electrification stops.

This is how a hydrogen train should work and from reports, it appears the Alstom Breeze based on a rebuilt Class 321 train, will work like this.

The Alstom Coradia iLint may have proved the concept of hydrogen power, but compared to other hydrogen and battery powered buses and trains, I’ve ridden, it scores poorly in terms of noise, vibration and harshness.

  1. Since Alstom is buying Bombardier it would be nice to have these built in Derby for CrossCountry and Chiltern. The low floor is a massive benefit.

  2. I think that the takeover is more likely to result in a hydrogen-powered Aventra, that would be ideal for South Western Railway to Exeter and CrossCountry.

    As Chiltern is at present virtually unwired. I suspect that hydrogen or electro-diesel wouldn’t be suitable or very efficient.

    I also think, that there is little point buying a train now, that can’t be converted to zero-carbon by 2050, as that would not fit in with the decarbonisation policy of making the country carbon neutral by that date, that is endorsed by all political parties.

    • I hope to ride in an Aventra this fall, but my main concern is the high floor as compared to the Coradia. Hopefully the Aventra software issues can be resolved soon. I would think the Covid shutdown should not halt software development.
