It was two years ago and the Brighton mainline was flooded. I was sat on a Southern Railway service stuck in Victoria for over an hour. The Guard made one grunt that Gatwick passengers could use the Gatwick Express. Not one apology or any other travel information was given.
Very different to the East Midlands Trains train manager who had advised us on delays, apologised etc. an hour earlier on the MML.
There are no need for guards on Southern Railway.
You can't judge all Southern guards and all EMT guards just by one experience with each TOC. I've received a fair amount of documented good feedback from customers and management for my use of the PA, however it only takes a quick look through twitter to see some colleagues aren't passing on info. Sadly it would appear these colleagues are more London based, and these ones will end up doing the entire metro grade out of a job eventually.
