The problem here is that there are many, many ways that 'the railway' could save money, by tackling genuine financial issues which are often hidden from sight. Instead, we saw a lazy 'report' from McNulty, acting as a government propagandist, which predictably said "get rid of staff". At pretty much exactly the same time, the industry was beginning to acknowledge and act on the newly appreciated risk of PTI incidents, and focussing in particular on that area. To manage that risk effectively requires people. The two issues are, unavoidably, at complete odds with one another. Those who actually carry out the daily task of operating the railways at the coalface, are in general agreed that single manning trains is simply not appropriate in the increasingly busy railway environment.
The railway sits on masses of needless financial waste. Others will be in a better position to quote specifics, but it is no secret that costs for everything from leasing life expired rolling stock, to leasing life expired revenue equipment, to getting Network Rail to come and change a lightbulb, are truly eye watering. As an example, TOCs pay vast sums to lease the current Avantix ticket equipment. It is old and inherently unreliable. If a machine fails, it must be sent to Atos for repair. A fixed fee is charged, which runs well into the hundreds. It doesn't matter that the TOC is already sinking £££s paying to use the stuff in the first place. And sometimes, it doesn't seem to matter that it comes back still defective. Replacement parts, such as batteries or a stylus for the PDA screen, are unfathomably expensive. The TOCs have little choice but to maintain an open chequebook with Atos' name on it, and the end result at best is poor quality, inadequate technology. No sensible industry looking to save money would deem such an arrangement to be appropriate.
Look at a newly installed signal. Even just a 'simple' peg, one signal on a post. Look at the enormous tonnage of metalwork that now often seems to be routinely installed with it, comprising a full access platform complete with fixed railings and safety barriers. How much does that cost on a network-wide basis? And why; how often do brand new LED signals need a bulb changed? And so on and so on and so on.... The real obscenity lies not with employing frontline staff to get the trains safely from A to B, but in the hidden costs that nobody ever probes, where massive sums of money are sent off to firm outside the railway for providing things at astronomical expense.
