An Exciting New Aventra

The title of this post is the title of an article in Rail Engineer.

It is actually dated the 31st of January 2014, so you might think it is out of date.

But surely, with the first Aventras appearing in service, now is the time to revisit.

I found the article this morning by accident and it is a fascinating read, Especially when you consider the article was written before the train had received any orders. Bombardier had actually just missed out on the Thameslink order, which resulted in the Class 700 trains.

A Blank Sheet Of Paper

The loss of the Thameslink order allowed Bombardier to start from scratch.

This paragraph indicates one of their start points.

And then we looked at it and thought we’ve also got depot engineers from Strathclyde to Surrey, all over the place, all looking after these trains in the field. How are they performing? Is there something we can do better there?

As the article says Aventra was reborn after Thameslink!

They also talked extensively to possible customers.

Suppliers

Suppliers were invited on board and given space with the design team in a new Design Office in Derby.

This paragraph described how everyone worked together.

We basically started from scratch, and in a completely different way. It isn’t engineering-led any more. It’s a joint collaboration of our depot people, our manufacturing guys, procurement and engineering.

I would describe it as a project-led structure similar to one that ICI used to use in the 1960s.

I wrote my first scheduling program to allocate the office space needed.

A Modular Approach For The Future

Each Electrostar had been different to the previous, but this sums up the Aventra philosophy.

Aventra will be a single modular product, capable of being easily modified for different applications but in each case referring back to the core design. So whether the actual class will be a 90mph metro train or a 125mph main-line express, it will have the same systems and components as its basis. In fact, Jon thinks that the distinctions are becoming blurred anyway.

They had looked forward ten years.

Away From The Wires

Aventra will be an electric train, but what happens, when the wires run out?

This was their solution.

So plans were made for an Aventra that could run away from the wires, using batteries or other forms of energy storage. “We call it an independently powered EMU, but it’s effectively an EMU that you could put the pantograph down and it will run on the energy storage to a point say 50 miles away. There it can recharge by putting the pantograph back up briefly in a terminus before it comes back.

I rode the prototype in public service in January 2015!

I was totally convinced that Bombardier’s battery trains have not even the smallest touch of Mickey Mouse!

Although the experience was magical!

Bombardier’s Iron Bird

Bombardier have borrowed the Iron Bird concept from the plane-makers.

This is an extract.

A leaf has been taken out of the aircraft designers’ handbook. They use something termed an Iron Bird – basically an aeroplane without wings – to test new systems.

Bombardier’s Iron Bird is a train without bogies. However, it does contain control systems, wiring looms and other bits of kit and it is being assembled at Derby.

I think that this shows, that they are not against borrowing other concepts from other industries.

The Most Affordable Train

The article describes how the train was designed to give the best whole life cost.

This sentence sums up the philosophy.

It’s actually about a 50/50 split between the whole life cost and the first capital cost. That makes it a bit more difficult because we’ve got be competitive on the first practical cost, but additionally we have to offer a really high availability, strong reliability, combined with much better energy consumption and less track damage.

As someone, who used to own a finance company, that leased trucks and other expensive equipment, the product described is the sort of product that leasing companies love. If the train is economical to run, if the first train operating company goes bust, you’ll still have an asset that other train operating companies will fight over.

Trains are also a predictable long-term investment, as well-built efficient trains have a thirty or forty year lifetime.

In my view the big winner of a train like this is the manufacturer, as they’ll get happy owners, train operating companies and passengers, which must lead to repeat orders.

Conclusion

I’ve never ridden a more well-designed, comfortable, smooth and quiet suburban electric train, than the Class 345 train in trial service on the Shenfield Metro, anywhere in the UK or Europe.
