I'm often a bit disappointed how car-centric some heritage railways are. Even when they have a direct connection to NR - timetables and facilities are sometimes centred around the station which has the biggest car park instead.
Rather echoing my notions as in post #62 -- but, if the railway wants custom, and thus money, in fair plenty: it can be seen as needing to exert itself to cater for car-parking -- the inescapable fact is that most visitors will come by car, NR connections or not. (Agreed, timetables should be displayed and easily accessible at all the line's stations.)
I recall a visit many years ago, to the Nene Valley Railway (I've told of this before on the Forums) -- my companion and I got talking to a couple of friendly volunteers on the line. After being duly complimentary about the railway, I ventured to mention my feeling of regret that the line had not been extended through to Oundle (that section remained in genuine use until a latish date), but terminated basically in the middle of nowhere. While the conversation continued to be polite and friendly; one of the guys proceeded to throw a metaphorical bucket of cold water over my head -- or one could call it administering a reality check -- by saying that the things which the large majority of visitors were keenest to get from the railway, were not to do with from where to where it went -- the most-desired things were good car-parking; acceptable, convenient and hygienic toilets; and courtesy from the railway staff.
My initial thought was, "what soulless, imagination-bereft blockheads the punters are"; but on reflection -- fair's fair: if one has a passion for the thing being visited, one will be ready to accept a degree of inconvenience / hardship in the course of experiencing it. If one is not thus passionate -- as "normals" visiting a heritage line are not; they'll be moved just by mild curiosity / nostalgia: then, especially when they are parting with a fairish sum of money for the experience -- they'll wish for the venue to furnish good quality, re everyday aspects of life which are important to them.
