The OP is proposing a similar stunt that has been covered many times before that it can be cheaper to fly from somewhere in the UK to a destination in Europe and back to a final destination in the UK for less than the rail fare. Its not a new idea and it just reinforces the idea that all rail fares in the UK are unaffordable.
Once again, most of them are!
You may be one of those super-planners who know to the minute where they'll be three months in advance, and also time-rich so slower, cheaper options are viable. Most people aren't, and so most people will pay more for their rail fare than it would cost to drive an average family car on their own on a marginal basis (which is the only basis that matters, because once you've chosen to be a car owner the fixed or near-fixed car ownership costs are in effect a subscription you pay regardless of how much you use it).
This is expensive. I'm not sure what you're struggling with to understand that. Rail is too expensive. How we reduce the prices is probably one for another thread - there are lots of ways rail could be made cheaper, not all of them involving whacking operating subsidy.
