In a major milestone for the £350m project, the first of Avanti West Coast’s new fleet of trains has entered crucial testing at Hitachi Rail’s Newton Aycliffe factory in the North East.

Carriages from a Class 805 train are being coupled together to mark the start of the extensive testing programme ahead of the planned entry into service in 2023 on the West Coast Main Line.

All basic functionality of the train, from brakes to engines, doors to toilets, will be put through their paces prior to the start of dynamic testing later in the year, when the trains will move under their own power for the first time.

The new fleet will be a mix of ten seven-carriage electric trains and 13 five-carriage bi-mode trains, with the ability to switch seamlessly between electric and diesel power. The electric trains (Class 807) will operate between London, the West Midlands and Liverpool while the bi-mode version will be focused on the London to North Wales route.

Phil Whittingham, Managing Director at Avanti West Coast said: “It’s great to see the new trains taking shape. The investment is a key part of our exciting plans to raise the bar for the UK rail industry, and our wider commitment to improve the customer experience and a more sustainable operation.”

The new Hitachi trains offer more space and a quieter journey compared to the diesel-only Voyager trains they replace. This will lead to a 61 percent reduction in carbon emissions.  Customers will also enjoy better and more reliable free Wi-Fi, at-seat wireless charging for electronic devices, plug sockets and USB slots; a brand-new catering offer and a real-time passenger information system that can advise customers of connecting rail services.

Jim Brewin, Head of UK & Ireland at Hitachi Rail said: “Our teams across the UK are working tenaciously to deliver more Hitachi intercity trains, which are proven to boost reliability and performance.

We look forward to Avanti passengers experiencing the transformation that follows the introduction of this brand new fleet.”

In April, an official investigation foiund that fatigue cracking in the area above the wheels of Hitachi-built Class 800 trains was a result of the rolling stock experiencing more movement than allowed in original designs.

Rail safety regulator the Office of Rail and Road (ORR) said cracks on trains discovered last year were caused by excess movement and aluminium corroded by salt in the air.
