The 180`s have to be one of the worst units that were made during the time of Alstom`s reliability troubles, other units had problems but not on the same scale as the 180`s over time the reliability has got better due to operators putting a lot of money into making them work.Even now GWR do not trust them enough not to brake down which is one of the reasons they do not use them at the weekends. I have used GC 180`s a few times, they are not the best inside but a refurbishment would sort out the tattiness, as with first class on the said company where a refurbishment of first class has taken place makes it much nicer to travel on. Not brilliant though, the ride quality is satisfactory at the best of times.
