This is all very interesting debate, but fares are not going to be reduced. Fine tuned perhaps to better match demand to capacity in some routes, but not reduced en bloc. We have a pretty busy railway with fares at current levels; reducing fares to increase demand would simoly result in more overcrowded trains.
Whilst anecdote does not equal evidence let me offer some personal experience from a relatively rare standpoint which only a few people in this country now have.
For well over thirty years I have had free rail travel nationwide. This now applies to Mrs BR and the BR children. In all my time with it I have lived in various places, but always walking distance to a busy station with frequent services. The cost equation of rail vs car vs other modes is therefore very different for me.
And yet, my family has two cars. We routinely drive to places that are within walking distance of a station, and some of these journeys are well over 100 miles. The train is usually more comfortable (we can read / sleep, drink…) and in many cases the train is quicker, especially given the increasing congestion on the motorways for the journeys we have to use. So: the train can be auicker, more comfortsble, and free but we choose to use the car. Why?
Because of convenience and flexibility. Yes it costs more, might take longer and be less comfortable but it is worth paying that ‘price’ so that we can leave at a time of our choosing, stop when we like, go visit places we might want to visit en route, and have the flexibility at destination to make shorter journeys there at minimal expense. When I visit my parents (who live almost next to a station with a decent service), I am rarely just visiting them. I am also visiting other relations, or taking them to a pub for lunch, or going to B&Q to pick up some stuff for their garden, etc. All much easier with my car up there.
We do, of course, also use the train for many long distance journeys, but these are typically for what might be termed ‘city breaks’, ie a visit to a specific location with no need to travel locally when there.
My point is that even with the cost of rail transport at zero, I need a car for most of my travel needs, even those that are easily completed by rail. I know talking to my friends and colleagues who have similar free travel facilities that they are the same.
Naturally, a rail forum is going to have a higher than average number of people for whom rail is preferred simply for being rail, and who may well plan their life around availability of rail services. But that isn’t how the rest of our society or economy operates.
