These mainly two-car long-distance units have been in use since the late 1980s now, and regardless of how many refurbishments and livery changes have been applied to them (see for example the East Midlands Trains livery - which is of course Stagecoach colours) over time, they have always been fault-prone, unreliable and often just plain awful to ride in.
Quite often the main problem lies with the toilets always not working properly, then the air conditioning packing in very easily. I dread the onset of hot / warm summer weather when I need to travel on a Class 158 because you always know that the air con will be defunct and the three skylight sections on the windows are forced open by the guard - which don't even provide much in the way of ventilation especially if the train is packed to the rafters.
These trains are just badly designed and constructed. Much of the interior upholstery is plastic derived and not metal. This causes a lot of inside noise when the train is in motion - the vibrations are deafening. Plus the fact that they very easily become very shabby looking anyway.
I wonder how long it will be before the TOCs realise that you can only polish a turd for so much before it just becomes a pointless exercise. Really, it's now well over 20 years these trains have been in service and I understand that the requisite life span of any train is at least 30 years intensive service before they can even think about retiring them, but these trains are so awful they should be consigned to the scrap heap at once and replaced with superior units such as the Class 175s and 180s. Even the 185s that operate TransPennine routes are much better - and more comfortable.
