Brain Teaser - How many of today's narrow gauge lines occupy former standard gauge track beds?

Are your little grey cells feeling moribund?
Need an antidote to endless Olympics on the gogglebox?.
Need an excuse to put off mowing the lawn?

By the way partial occupation also counts as does closed but extant narrow gauge lines.

 

Teifi Valley
Bure Valley if 15" counts

 

Waterford and Suir should qualify.

Moribund Foyle Valley Rly in Derry

 

Go down to 10 1/4" and you also have Wells & Walsingham

 

Rudyard Lake?

 

Launceston.

 

Obvious: Kirklees Light Railway.
Moderately obscure: Final few yards of the Festiniog Railway (into Blaenau Ffestiniog).
Technically: All of the Ravenglass below Murthwaite (first 3', then 15", then 15" and standard dual gauge, then back to just 15").

 

Wasn't the Teifi Valley originally Broad Gauge (7ft) before becoming standard gauge? Or am I thinking of Launceston?

Launceston was LSWR so not broad gauge

 

South Devon railway, West somerset railway......

 

It's only a guess but what about that NG line next to the GWR at Toddington? And is there still similarly a NG line at the Midland Railway Centre? (And can we count the old 15" gauge line which was at Carnforth).
No idea which of these are on actual trackbeds as opposed to just alongside.

 

Yes, found out that the Teifi Valley was indeed converted from broad to standard gauge and is now narrow gauge - I always thought there was one...

 

No - the line that TVR occupies was built by GWR after BG days.

The TVR line was built by the broad guage Carmarthen and Cardigan Railway in stages in the 1860s. It was taken over by the GWR in the 1880s.

 

I know and the original question was about former standard gauge lines.

 

Err the reply was to Gareth's comment about Launceston having been possibly broad gauge.

 

I take that back. The bit the TVR occupies is on the GWR's later extension to Newcastle Emlyn, so would never have been broad guage.

 

Makes life a whole lot easier for the rest of us if you quote the relevant post.

 

Speaking of the original question - there is still at least one more line out there that nobody has mentioned.
