Most Heathrow Express Class 332s recalled after ‘crack’ in underframe

The majority of Heathrow Express trains have been pulled from service as a “safety precaution” after a fault emerged during a routine maintenance check.

Train drivers union Aslef told the BBC that there was a crack in the underframe of one of the Class 332s, discovered on Sunday by Siemens.

The fleet was recalled and each train will be “thoroughly inspected” over the coming days by a specialist team at the Old Oak Common depot.

In the meantime, Class 360s, usually seen on the Heathrow Connect service, will run every 15 minutes between Paddington and Heathrow over the next two days.

The Heathrow Connect itself will be suspended during this period, with passengers who wish to use the service being advised to take the 140 bus from the airport to Hayes & Harlington, followed by a Great Western Railway (GWR) service to Paddington.

GWR will also be rolling out extra trains between London Paddington and Hayes & Harlington.

Heathrow Express director, Fraser Brown, said: “While we regret the inconvenience this will cause to our customers and airport colleagues, safety remains our top priority.

“We are working with Siemens engineers, who manage our depot site and the maintenance of our trains, to understand the extent of this issue. When we are aware of what we are dealing with, we will be able to make a decision on when a full service will resume.”

Since the Heathrow Express Class 332's do have problems. Northern Rail's Class 333's may also be affected at some point unless its just the HX Class 332's that have problems.

At least heathrow express trains are made by siemens, not bombardier as used on london transport, with their god-awfull all sideways seating and constant stream of announcements.

Pete, the Overground trains are a completely different kettle of fish, and the seating arrangement has nothing (or very little) to do with the mechanical specification of the train.

The seating arrangement on LU stock is to fulfil a totally different requirement to suburban surface stock. And the announcements are governed by TfL/LUL not by the train maker.

Pete: The Heathrow Express trains were made by CAF. The Heathrow Connect trains are Siemens. The seating arrangement on the Overground is appropriate to the metro-style stopping patterns, frequency and average journey length on the system. The Overground 378s are excellent trains for the work they do. The previous trains with 3+2 seating were a disaster to get on and off of when busy. Andrew G: So, some other trains may be affected unless they're not affected? Not sure this adds anything.

The class 332 and 333 were sold by Siemens while Siemens and CAF were in a contact to sell them, CAF built the bodies, and Siemens electical equiments were used. After these trains were in sevice, both companies sell their own trains.

Similar structural cracks have been found around the majority of yaw damper support brackets on the 10 year old CAF built trains serving the Dublin / Cork line in Ireland. Major body structure work required. CAF have admitted bad design but have still washed their hands of it.
