At Lime St, Northern employ the dispatchers for all trains apart from Avanti services. Northern also employ the staff in the ticket office, barrier staff and the station ops controller as well as traincrew based at the station.Network Rail don't provide station/platform/dispatch staff at any of their managed stations in London. Southeastern staff London Charing Cross and Cannon Street, Southern staff Victoria, and so on.
Avanti have traincrew and their own dispatchers based there
TPE have traincrew based there and a small handful of non safety critical platform staff.
Network Rail employ the station announcer, security and passenger assist staff.
Ultimately, NR staff have no experience with train operations. A more collaborative approach was required on Monday and by the sounds of it, that did not happen.
