As a tourist, and presumably buying your ticket on the day of travel at Winchester Station - you would pay the highest price.
People living in Winchester commuting to London will have season tickets, local leisure travellers these days buy tickets in advance if they have advance notice when they will be travelling, probably on ine, and thus the situation is not as bad as it seems to you.
Having said that, any journey of up to 200 miles is just as quick by car door-to door - and bear in mind that our gas costs twice yours too. The result, when I am going to train shows I fill the car (LS400) with chums and we have a nice friendly trip there and back, chatting so much we hardly use the radio.
What makes, particularly London, different is the cost and difficulty, of parking - costing perhaps £40 (say $60) per day, and the slow speeds in the rush hours too, of course.
However, commuting is a different subject. There is a niche for rail between 200 - 500 miles, after which air is better in spite of the security hassle. A few trains in the UK do cover all their costs, but the necessary comprehensive service hardly ever does. Our busiest rail route, the West Coast Main Line (London - Birmingham - Liverpool & Manchester - Glasgow) for example, has an average seat occupancy of a mere 20%. Since the train s are full for a couple of hours in the morning and evening, you can see that for the rest of the time they are probably only 10% occupied.
But when mentioning efficiency, it is necessary to multiply the rail-road quoted figures by five to get a proper picture for they always quote consumption per passenger mile assuming all seats were occupied.
When it comes to ordinary people, most never use rail travel at all. It has developed into a service for the middle classes and business people, only a small number finding it useful for social and pleasure travel. The exception is commuting, where all classes use trains going to and from work.
Electric cars will eliminate any fuel-efficiency claims railways possess and autonomy will eliminate the point of being able to work while you travel by train too. So the medium term outlook for passenger rail travel does not seem particularly bright to me.
