Remember that little problem with opening Cannon Street on a Sunday when Charing Cross mainline is closed and overground services run from Cannon Street instead? Well, it's cropped up again.
This time, LUL's short-staffing problems are compounded by the fact that the mainline train operators did not bother telling LUL about their plans until rather late in the day. So LUL has only been able to muster the resources to open until 1pm.
It's another triumph for 'customer service', and another source of grief for staff.
