Yes Iíve just had that confirmed - train hit something unknown followed by
huge loss of air, traced to broken pipe joint under nose of train.

Seem to remember something similar with a 180 versus a pigeon on the Cotswold line some years back. The 180 lost all air.

But was the pigeon alright ?

No point sending a fitter from Exeter. They wonít know anything about the train.

Hitachi have numerous fitters in the region, including travelling fitters, the nearest available fitter would have been sent.


I wasn't really just talking about Exeter. It was more a question of: has the change to Hiatchi staff looking after / fixing the trains (as opposed to GWR staff which is the case for the HST's) meant that staff who can fix issues will now take longer to get to incidents compared to similar GWR staff for HST's? 90 minutes away seems to be quite a distance away!

Thereís Hitachi maintenance staff in Bristol, Laira and possibly Long Rock.  Thereís also travelling Hitachi fitters for the South West based at Exeter, Plymouth, Truro and Penzance so for minor issues it shouldnít take any longer.
The nearest maintenance facility is obviously Bristol, so any fault requiring specialist tools may have to come from Bristol.

No specialist tools needed, one thing that was very much against getting assistance to the train in a shorter timescale was the day long closure of the M5, no matter what contingency plans you have in place - within reason- can take into account exceptional occurrences like that.

Might I suggest that there might be some corporate relief at Hitachi and GWR that this train didn't simply break down, and that the incident was caused by an external factor, with low probability.

Not that I am saying that if they can, steps should be taken to investigate and mitigate a recurrence.

I find that hard to believe, I canít see how an object would be able to access any of the pipes under the nose of the train.  Considering the delay cost runs into a 5 figure sum, one wonders wether Hitachi are trying to wriggle out of it.

I am aware of at least one case in which a modern EMU was disabled after striking a goose, the impact of which broke an air connection.

So yes it is possible. If such incidents recur regularly then that suggests a need to make the relevant parts of the air system more impact resistant or easier to isolate.
If it was a very rare event, then (goose)shit happens!
