Just to touch on the subject of having every station gate lined and manned.
You'd need three staff at every station (to make sure that there are always two working if one is on a break), so this is 3x60=180
You’d need at least three shifts so 3x180 = 540.
Now each CSA earns about £26,000 (actually a little more)
So 540 times £26k is about £14m.
That £14m doesn’t take into account the fact that you’d need more ancillary staff to support that massive growth in CSA numbers;
More managers, more HR, more Payroll etc etc etc.
Let’s not forget the actual cost of the ticket barriers themselves, which I would imagine would dwarf the staff costs, each single unit being extremely expensive. You’d also need to factor in building some form of break room at any station where staff are expected to man a gate line. The costs are rising again…
also, all the CSAs are entitled to catch the last train home, so I’m not sure how you’d keep the stations manned then.
How much would you be expecting to make from tickets if this was the plan?
