The quickest and most effective way to help people get richer is lower taxes.
That's just as much of a 'painkiller' as a fares cap. The
only profitable railways are those that either A: make their money through side projects like housing or retail (e.g. JR East), or those that cut back service to only include profitable, high-fare routes such as commuter and intercity services (e.g. SNCF, or at least as much as they can get away with).
The former's not really an example of rail being 'profitable' necessarily, just a joined-up way of integrating housing, shopping and transport - the rail revenue on its own doesn't cover the costs. The latter drastically reduces rail's function in society - the state actually loses out significantly in other ways if you cut back unprofitable rail services or increase fares, as people lose access to jobs, young and old people get out and about less, and society gets more car-dependent which as we all know has many negative effects on society and the places we live.
In the short term, anything that the railway does to alleviate the symptoms of the cost of living crisis needs to avoid making the ailment worse, and be quick acting.
[DEVIL’S ADVOCATE] Given that the fares cap has had, essentially, zero impact on demand, demonstrating (yet again) that demand for rail is usually price inelastic, and that rail is disproportionately used by those in higher income groups…
…the best way for rail to contribute to the cost of living ’crisis’ is to put fares up by more than inflation, and use the cash generated to fund essentials for those who really need help. [/DEVIL’S ADVOCATE]
Quoting the above two as they argue the same point.
If you want to look at the railway on its own, fully siloed from everything else, then the above statements are objectively right. Rail costs a lot to run, even more to make better, while few people use it.
And indeed, if your goal regarding rail is just to keep it running to a bare minimum, rather than looking at reasons why the railways are a good thing to have, then it's correct that we should be spending less on it.
But that completely ignores what'll happen if do let rail usage stagnate or even decline - the negative effects to society of people
not using the railways enough. A society that values the positives of rail usage (and public transport in general) does function better than one that doesn't. It makes the places we live nicer (through less congestion and more walkability), makes getting around a safe, reliable and affordable option for as many people as possible, improves one's health - I could go on and on but we all know this stuff (if you want it in full, sites like Campaign for Better Transport lay it out well). Essentially rail is not just a cool mode of transport, as we on this site all know, it does create more active economies and higher quality countries - there's a reason why the Swiss don't complain about the £400/person annual subsidy for rail - it's because the money is proven to be well-spent.
So basically if we don't want to look further ahead than the next general election, looking at places to cut subsidy in order to bring short-term relief to the economic troubles of the country, go ahead, do all the austerity that you want, and give the freed up money back to the people through lowered taxes etc. - but after that, within a decade or so, you'll notice that the motorway congestion won't have gone anywhere, there still aren't any jobs in regional centres, and those on the lowest incomes still can't feasibly reach a workplace without buying a car, so likely will remain on benefits.
Or alternatively we could spend more on public transport, set actually clear mode shift and passenger growth targets, then make the money back in good time through the increased economic activity, have a happier and healthier population, and might also have a chance at achieving some of the ambitious net zero targets.
