Introduction

This section of the website is based on the 'WHR Maps' website originally authored by Steve Harris, and before that it was also available to be purchased as a cd as part of the Society's fundraising for the rebuilding of the Railway. Once the railway was complete Steve subsequently donated the WHR Maps to the care of Cymdeithas Rheilffordd Eryri. It was therefore incorporated into its main website as is seen here with the content unchanged although the navigation has been altered slightly.

The Maps & Plans

There are several sets of maps or plans to choose from accessible from the main menu above or by clicking on the links below. This will then allow areas to be selected by clicking inside the rectangles until the desired map is displayed. In some cases it is possible to jump from one resolution of map to the other, or or between the TWA maps and gradients. Some of the maps are also available in large resolution.

  • Gradient Profile (as proposed) of the new railway between Dinas and Porthmadog. There will be many places where this turned out to be slightly different once the railway was finally constructed.
  • TWA Plans or Transport & Works Application plans submitted as proposed construction plans (including limits of deviation) of the railway from Dinas to Porthmadog.
  • Large TWA Plans details as for the 'standard' sized plans above.
  • Standard WW1 Ordnance Survey Maps dating from before 1916, which, while not actually showing the W.H.R., do show the N.W.N.G.R., the P.B.& S.S.R. earthworks, and the Croesor tramway (see "Background", below).
  • Large WW1 Ordnance Survey Maps (c. 1916) Higher resolution version of the Standard WW1 maps.

Background to the WW1 Maps

The Welsh Highland Railway between Caernarfon and Porthmadog as it is today, consists of several sections of earlier railways. To help in the understanding of the WW1 maps these are described below:

Caernarfon - Dinas  This is part of the former standard gauge line from Caernarfon to Afonwen. The 1916 maps reproduced here show this railway as the L.& N.W.R., Carnarvonshire branch. These maps also show the Nantlle tramway where it deviated from the standard gauge route. 
 Dinas - Rhyd Ddu The trackbed of the former North Wales Narrow Gauge Railway. This became part of the Welsh Highland Railway (1923-1937), but is shown on the 1916 maps as the N.W.N.G.R. There was also a branch to Bryngwyn that, whilst it is shown on the maps, is now a multi use footpath.
 Rhyd Ddu - Croesor Junc The trackbed of the Welsh Highland Railway (1923-1937). This railway is not actually shown on the 1916 maps, but has been drawn on by hand to show its (later) route. The earthworks and forestry sidings of an earlier attempt to build this section are shown (the Portmadoc, Beddgelert and South Snowdon Railway or P.B.& S.S.R.).
 Croesor Junc - Porthmadog The trackbed of the Croesor Tramway, which became part of the Welsh Highland Railway (1923-1937). The 1916 maps show this as the Croesor Tramway and include a short section towards the Croesor valley from Croesor Junction. Also note there is no connection with the Festiniog Railway in Portmadoc.
