Ordnance Survey: Definitions & Abbreviations?
Posted: Sun Jul 05, 2015 12:51 pm
I have recently been exploring the Ordnance Survey, 1:2500 maps of the late 1800's & early 1900's [that are currently available via http://www.old-maps.co.uk] looking at Railways, Tramways & Mineral Railways in the Swansea & Gower area.
My instinct suggests that a Tramway could relate to a narrow gauge track, whilst a mineral railway could relate to a standard gauge (4' 8½") track.
Whilst looking at the Mineral Railway from Cenfgyfelach Colliery, northwards to (the former) Llangyfelach station I spotted the endorsement 3ft R.H. (see here), I haven't seen this abbreviation on any other Mineral Railway, nor Tramway, neither can I find any reference to the abbreviation R.H. on the O. S. website. Are there any thoughts as to what this abbreviation might mean?
