The NVR was one of the early preservation schemes and should be much bigger and better than it is but has been overtaken by many other lines through lack of ambition. Extending a heritage railway is perfectly feasible as the GWR, Llangollen and many others railways have shown. Some, such as the Lynton and Barnstaple and Helston schemes, have started from scratch. The NVR could and should have secured the trackbed to Oundle 30 years ago.
*Sigh* when will you start using some basic facts and investigation before posting your comments?
Right - Let's start with the Llangollen's recent extension - 2 miles which has cost them £ 1m - so it costs about £ 500k / mile to extend a heritage railway.
Yarwell - Oundle is about 7 miles - so such a project will *easily* cost over £ 3m.
This statement in particular "The NVR could and should have secured the trackbed to Oundle 30 years ago." is utter bollocks and shows how little you know about the NVR and how it came into being. The NVR didn't OWN any of it's trackbed at its inception - instead it based what rolling stock it owned at the British Sugar site in Peterborough. The only way it obtained a running line was as follows:
"In 1974, the Peterborough Development Corporation (PDC) bought the Nene Valley line between Longville and Yarwell Junctions and it began leasing it to the PRS to operate the railway a major milestone in the society's history."

The NVR was by the late 70s running a 6 mile heritage line - a significant achievement. But was doing it wholly volunteer labour and on a shoestring.
They then, rightly, focused on extending into Peterborough itself - though their terminus is some way from the city centre.
The big problem they have is they are not in a 'natural' tourist area - the only other heritage line of any scale which I can think of that has a similar issue is the GCR. All the others, particularly of those early pioneers benefited from being in or close to other major tourist areas - NYMR in North Yorks national park, WSR - Minehead a seaside tourist destination, Severn Valley Railway - Bridgnorth & Ironbridge, Swanage - Swanage & Corfe Castle, Bluebell - Sheffield Park & South Downs and so on.
Peterborough doesn't compare to any of those on any objective level. Oundle isn't a tourist destination full stop - it's a small, quite pretty, market town. That's it. It's no more a tourist destination than Wellingborough. It's certainly not comparable to Stamford (a short distance away) because Stamford has Burghley House.
The L&B is not a fair comparison in any way - the costs of building and running narrow gauge are FAR less than standard gauge. Once again they're in a major tourist area so benefit from passing trade.
The NVR has survived, largely because it's so close to the country park which the PDC developed as part of developing Peterborough - but as the number of heritage railways has mushroomed in the last 30 years the NVR has lost some of its early attraction to the enthusiast market - somewhat unfairly. So it has become more reliant on the family market and targets many of its events accordingly.
They are currently appealing for funds to overhaul one of the line's stars - Thomas - which will cost over £ 150,000 - if they're having to appeal for that, the chances of raising £ 5m to extend to Oundle (before you even factor in the running costs) seems more than a tad unlikely.
And a four-track railway is hardly comparable to a single track road. And capacity for what exactly - lines of cars with single occupants, or trains every few minutes with hundreds on board ?
I didn't compare a 4 track railway with a single track road. I compared a 4 track railway (MML) with a motorway (M1) and pointed out what the likely dimensions for a 2 track railway were against a single carriageway road - which is an entirely reasonable comparison.
