The WSR? There's no serious prospect of running services to Minehead, even as an experiment. Apart from anything else, it's a long slow line (probably more than two hours up and back, so needing extra units), and paying for all the signalboxes/crossings to be manned would be very expensive (the WSR volunteers are not going to be willing or able to do this for free). And the WSR would not want even the minimal changes to the stations needed to operate a national rail service - it's a *heritage* railway, it would spoil the atmosphere. Plus the heritage service operates on most days for parts of the year, so this would clash with the national rail service, with the line being single track. Finally there's the issue that currently for a national rail service to run onto the WSR a token has to be sent by taxi to Taunton!
I would say there is a "great" prospect if the relevant stake holders came together: WSR - track, GO-OP - rolling stock/on train crew, GWR/X Country - connections, Network Rail - Signalman and other staff if necessary, Butlins - publicity/encouraging its customers to travel by train, Local Councils/authorities - championing the cause and somebody to put up a modest amount of cash (if needed) - Government most likely?
The rolling stock that would be used is relatively new so it would have better acceleration and braking than a steam engine or an old diesel so could traverse the line quicker and while Im not saying that you run at 60 - 80 mph Im sure a compromise could be found so trains could run at 40mph also as I said in post #356 the trains would only stop at a few WSR stations so I reckon it would be a competitive alternative to the car
Depending on the timetable you might only need "one engine in steam" so the line could be operated as just one long siding so no need for signalman, if however you do want to run more than one train then either you offer to pay current volunteer WSR signalman to work mornings or evenings on a two year contract or get some Network Rail signalman to do it.
If after for two years it is loss making then scrap it but if it is breaking even or making a profit then see about automating so from start of service till 10 and from 17.00 till end of service it is all automated but from 10.00 till 17.00 you have a bloke pulling levers so it keeps the visitors happy.
Next time you visit a stately home or any other historic building open to the public look around FORENSICALLY and after a while you will start to notice the Fire Exit signs, Fire extinguishers and all the other host of Health and Safety stuff you need to have to be open to the general public. The reason why I emphasize forensically is because a way has been found to put in the stuff that is needed but at the same time keep everything the same as it would have been in the past.
Also I saw a TV show where the presenter went to this castle and interviewed the bloke who owned it and he said that back in the day his Dad/Grandad brought the castle and literally threw the doors open to the public so he had people walking along the ramparts where they could have fallen off or going to the top off towers where they could have toppled over the edge. Obviously today with modern H a S there is now way that could carry on so now they have a simple single metal rail along the ramparts and at the top of the towers and 99% of the visitors would either not notice or assume the railing was there when the castle was built.
My point is that WSR and Network Rail could work together to do only what is absolutely necessary while at the same time keeping the atmosphere so the vast majority of visitors would not even notice (for example if lighting is needed then just put in some Victorian lampstands) also the modern stuff would only be at a couple of stations so the rest could keep the oldy woldy "atmosphere".
Also I while ago the WSR was on the verge of financial collapse and while I dont know what there finances are like today Im guessing they are still watching the pennies. So, Im not saying that WSR let GO-OP or anybody else use their infrastructure for free what I am saying is that WSR have a "pile of old rope" (track,stations) they are not doing anything with most of the time so if somebody wants to "rent" a bit of that rope why not let them or take a cut of the tickets sold and then plough it back in to the railway so they have a railway in the first place.
Post #356 covers this, The public service would be mornings and evenings only. But if WSR do want to do occasional evening stuff then a rail replacement bus every so often would not be the worst compromise in the world.
Having to take a token to Taunton is not ideal but as I say live with it for two years and if it is a success do whatever you need to do with the signaling so trains can rum seemlessly between WSR and Network rail.
This could also be a good earner for GO-OP because all over the country there are heritage railways that are either connected or want to extend to connect with the national network but would not want the hassle and hoops to jump through/be able to run there own passenger service so what GO-OP could do is be one stop shop for a heritage railway by offering a train, crew and doing all the paperwork for them in one package with the heritage railway just sitting back and collecting rent or a cut of the tickets.
Finally, virtually all heritage railways were set up initially with the idea of restoring passenger services and possibly freight and while most have had to modify there plans and chase the tourist market to cover day to day running costs the idea/hope is still there also the amount of threads where people talk about how much they wish So and So heritage railway would extend to meet up with the network is infinite, the problem is that where ever you came from on this issue you always run into the same 5 letter word and that word is MONEY or to be more precise lack of.
So if this idea was tried and worked then it could be rolled out across the country for example Ive already said about Swanage
Swanage Railway recruiting a Chief Executive | RailUK Forums post #107 but also who fancys a steam/heritage diesel ride from Broadway to Honeybourne on an extension payed for by a Broadway or possibly Toddington, Winchcombe to Birmingham commuter
GWSR Broadway to Honeybourne redundant track bed | RailUK Forums or being able to arrive on a steam train at Padstow payed for by a Bodmin - Plymouth/London commuter?
