Hatched red 522 14% All engines are allowed

Red 1280 34% All engines allowed except King class

Dotted red 285 8% Red engines (see below) are permitted at speeds no more than 20 mph (32 km / h).

Blue 320 9% Dotted blue 150 4% Blue engines are permitted at speeds no more than 25 mph (40 km / h)

Yellow 695 18%

Unpainted 495 13% The shaded reds routes included Paddington to Bristol Temple Meads, via both Bath and Badminton; Reading to Devonport via Newbury; Bristol Temple Meads to Taunton; and Paddington to Wolverhampton Low Level via Bicester. Further routes were raised into this category after nationalization: from Wolverhampton to Chester via Shrewsbury; and Bristol to Shrewsbury via Abergavenny.

Up to two coloured discs were painted on the cab of GWR steam locomotives and some classes of Western Region diesel locomotives to show that the maximum axle load of the engine must not exceed a certain value, the absence of such circles means that the restrictions on the locomotive were as shown in Table 3.

As with the power classifications, the locomotives provided for the GWR during World War II were given GWR weight limit colours. For example, Class J25 LNER engines that had route 3 availability on this line were placed in the Yellow GWR route constraint.

Corrections were made from time to time based on operating experience; for example, the 5700 class (which had an axle load of 17t) had a weak hammer blow, so it did less track damage than other engines with their axle load; accordingly, in 1950 they were reclassified from “blue” to “yellow”.

Transport for Wales is delighted to announce the opening of the new Bow Street station.

The first train stopped at the station in Ceredigion, mid Wales, at 9.12am on Sunday 14 February, providing a link to the national rail network for the community of Bow Street for the first time since the former station was closed in 1965.

It is the first station to open in Wales since Pye Corner in December 2014 and Transport for Wales’ first since taking over the Wales and Borders network franchise in 2018.
