Just looking through FB, and the UK Railways have a tonne of problems, 

TFW Overcrowding 
XC not enough trains/overcrowding 
EMR Norwich to Liverpool overcrowding
GC 180's reliability
Replacement for TPE Class 69
Northern's 156/153 replacements (apparently Northern want 185 for that)
Avanti as a whole 
Appauling state of the Class 800 on LNER/GWR (seats, relability etc)

I think the only good train company really is East Anglia 


An absolute dumpster fire
