I was wondering the other day how many heritage railways can boast an 'original' signal box.
My definition of 'original' is:
1) Box was serving as the box at the site pre-preservation (not necessarily the first box built at the location)
2) Box building has not been moved post-preservation from another location on-site.
3) Frame installed and worked pre-preservation. (not necessarily the first frame installed at location). Locking alterations and addition of levers permissible.
4) Box is not a reconstruction containing a small amount of original material to the location (e.g. Bridgnorth, Hampton Loade SVR).
5) Box is in use.
My list currently is:
SVR: Highley, Bewdley North, Bewdley South
WSR: Blue Anchor, Williton
L&HR: Lakeside, Haverthwaite
ELR: Ramsbottom, Townsend Fold
YDR: Embsay
Wensleydale: Bedale
SDR: Staverton Crossing
RHDR: Hythe, New Romney
EOR: North Weald
NYMR: Goathland
CVR: Leekbrook Jn.
Mid-Hants: Alresford
Bluebell: Horsted Keynes
IoW: Havenstreet
Nene Valley: Wansford
Bala Lake: Llanuwchllyn (the fact it now works a 2' gauge line is permissible).
Strathspey: Boat of Garten South
Can anybody add any others? Or knock any of the above off the list?
