I suggest it's the lack of on train ticket checks that makes for fare evasions.
You can't check every ticket on every train. A good revenue protection strategy will include lots of different elements, including:
- Making it easy to buy tickets
- Have a decent fares structure - the old British Rail structure was excellent in this respect
- Install ticket barriers at large stations and for journeys where carrying out onboard checks can be difficult
- Carry out onboard checks, particularly on long-distance routes where there is typically a longer time between station calls
- Carry out high profile revenue blocks
- Have a Penalty Fares policy
- Make use of investigation in the 'back office'
- Prosecute those who do not co-operate with train company investigations
And that train fares in the UK are extortionate!
Some, but by no means all, fares are extortionate.
Don't always think fares abroad are always cheaper because they're not. I recently visited Bordeaux and arranged travel more than three months ahead. Eurostar/TGV was £200+ one-way (which was led by the TGV price from Paris). I ended up flying.
That being said, absolutely remove the private interests from the railway.
I disagree. There will always need to be, and always has been some sort of private involvement. The state is not always great at operating large organisations.
I’ve often felt I had to drive rather than use the train due to the extreme prices
I think it's horses for courses. The train won't always be the best value or most appropriate way to travel. For example, I often travel to the north-east:
If we're going to the weekend it's good to have the car with us so we can visit the countryside - there's sp much to explore. Plus we can just dump everything in the boot of the car.
If I'm going for a work meeting then the train wins for going there and back in the day.
I've never tajen a flight to the north-east but I have taken a flight to Scotland on a few occasions, normally because the times have worked out better. I've also taken the train to Scotland.
TOC's are effectively on a management contract, so any fare evasion is effectively stealing from the taxpayer.
Many TOCs have targets set by the DfT and can earn a larger performance fee if they exceed these targets. Ticketless travel is often one of the targets.
