360s because heavy maintenance is done at Northampton. I believe they are/will be utilising Bedford Cauldwell a lot more nowadays so theoretically it'll get better on that side, but we do still see various failures and short formed sets, especially during the current heatwave. Also happy to be corrected on that
Drivers’ cab aircon being weak and failing entirely during hot weather was the cause of yesterday’s issues, which resulted in the Connect service being decimated (described as “more trains than usual requiring maintenance”).
Enough units were involved that Connect became essentially unviable, with Nottingham IC services calling additionally at Bedford and Wellingborough, and Luton/airport passengers directed to Thameslink (a contingency which worked pretty well, to be fair). This is likely to repeat today and tomorrow, at least to some degree, given forecast temperatures.
It has also been blamed internally on the units needing to be dragged to Northampton, but is a recurring issue that doesn’t seem to occur with other Desiro fleets, perhaps suggesting the 360s were specified differently from new. It’s also an issue that has been raised time and again as it happens during every summer heatwave, yet never seems to be properly dealt with.
As long as they see better availability than their GWR and LNER cousins...
Indeed. They’ll be doing well to be more reliable than the 222s which have AIUI been one of the most reliable fleets in the UK for much of their tenure at EMR. The thing that seems to have changed recently is the maintenance regime.
Based on the current showing, where 810s haven’t even survived initial testing without needing complete rewiring, I’m not too confident…
