Blue, Yellow - Up Line (The sky think up) Brown, Green - Down Line (The ground think down) You also have pinks and other colours which can be used for up and down lines. RIP Feltham Panel 1 Log in to reply |

" said:Blue, Yellow - Up Line (The sky think up) LMR used to use red for berth tracks (but that would have been in Absolute Block areas and probably before the 1980s). There were other colours that could be used where there would otherwise (for whatever reason) be two adjacent TCs with the same colour. I hear it said (I'm sure someone here can confirm) that Wembley Main Line has a black TC on each line between the Euston & Willesden control areas... they were installed at different times and someone forgot to check the Euston colours carefully enough when the Willesden area was being planned (or so 'tis said)! These, of course, are track circuit colours (it was the (G)WR that used all black for TCs). For lines not track circuited, a bluish colour was very common. On the Eastern Region (not sure quite how old this was, and again would probably not be the case after the 1970s) goods lines were a purplish-pink colour. I think the GW used grey for the same purpose. Of course some older diagrams survived until much later, often with additions & alterations added to the original, so you might in some cases find these older standards alongside bits that conformed strictly to the newer ways.

Please don't shoot me, I am only the messenger! I related the story of colours to an expat Pom here in Australia who wasn't aware of it. "Look up and you'll see the sun (yellow) and the sky (blue). Look down and you see grass (green) and dirt (brown)". My expat Pommy mate said "If that were true and the story originated in Britian, the colours used for Up tracks would be light grey and dark grey"!!! ![]() ![]() Not fat ..... fluffy!!
