So now that Southern and GTR have merged the Twitter teams, how do regular users of the service find it? Is it as good?
It's the same Twitter address and can only de described as total and utter crap. It is a significantly poorer service, and gives no information at all. They tend to say there is disruption and give a link for you to check. You need to select that link then the link within the resultant page, then enter your stations and then get the info that may or may not answer your original question.
The only real solution is to follow @southernmalachi who is a volunteer who tweets most information about peak hour delays and cancellations. He can't do short forms as that information is only released at the station when it is too late to be of any use to anyone!
