I know road travel isn't subsidised, but imagine if it were. Would we be trying to differentiate between journeys "worthy" of subsidy ?
The annual roads budget would suggest otherwise!
About the only use of railways that isn't at least arguably worthy of some degree of subsidy (if necessary) is the "meta-use" - ie railway enthusiasts travelling by train for the sake of travelling by train and not actually spending anything at a destination. Everything else potentially (important word) either removes cars from the road or contributes to economic or social well-being. Now, the degree to which different benefits are worth subsidising is a different matter....
I agree. Perhaps we should ban things like rover tickets, because why should enthusiasts be subsidised making pointless journeys?!
Many rail services are undoubtedly worth subsidy, but I am not sure taking leisure passengers around on diesel trains is that high up the list.
Again - what’s your proposed solution? Close the railways? Ask people what the purpose of their journey is and charge them accordingly?
The big difference is that everyone uses the roads. A minority of people use the railways, so we should be more thoughtful about what gets subsidised and whether that provides good value for the taxpayer.
The fact that a minority use the railways is completely irrelevant when you’re considering whether the economic externalities justify the subsidy.
