I got quite a few replies most informing me that there were absolutely
no cost advantages for the narrower guages and that my suggestions were
a complete waste of time.

Quite a number of tourist railways which have been built on disused
trackbeds of standard gauge railways have gone for a narrow gauge - see, for
example, at opposite ends of England the South Tyneside Railway and the
Seaton Tramway.

If you're accepting low speed & limited capacity - which is almost
inevitably going to be the case for a preserved line with a light
railway order - then there are advantages in lighweight rails and
light, small rolling stock - and light, small rolling stock is
much easier to find in NG than SG.

That said, it'd be interesting to compare the cost overall for one
of these NG lines and, say, the Tanfield, which uses SG stock which
isn't that much larger or heavier than many NG lines.
