Does delay repay apply to overcrowding to the point you cannot board on Greater Anglia? I recently claimed back for this on South Western Railway and they were even advising us to do this and had area on form just for these situations but Greater Anglia don't say anything about this. GA tend to use different reasons for cancellations than other operators for stock issues. For example more trains needing repair at same time than usual is used by GWR and SWR but with Greater Anglia it's always a train fault even if it's due to lack of stock. I've also seen reasons get changed later on. For example a train fault delay delay being attributed to a freight train that I guess it got stuck behind as it missed it's path.
