Cowlairs Tunnel details

Recommended Posts

Hello all,

 

Wasn't quite sure if this was the correct place to ask this or start it on the signalling site, however, I decided on here so I apologise up front if it is the wrong place.

 

I'm modelling the first section of Cowlairs incline and Tunnel, out of Queen St. I know there is a trailing and facing crossover in there and a ventilation shaft, viirtually above this crossover, however I need to know if anyone at all knows what construction material was used on the Tunnel bore lining itself, i.e brick, stone or other.

 

Also, on the way down the incline protecting the aforementioned crossover and entrance to the station throat is a ground signal. I cannot for the life of me find any reference photos or drawings of this signal at all. I know its a ground signal, likely to be two aspect ( yellow and red - but I could very easily be wrong and also most likely to have a platform indicator attached to it somewhere!)

 

Many thanks in advance if anyone has any knowledge.

 

Andy

don't know if the queen st. end has been re-signalled since, but there's a 1985 cowlairs/queen st. signalling diagram at http://www.s-r-s.org.uk/archivesignals/brscotsig.html

 

1985 diagram (on p.10) : http://www.s-r-s.org.uk/archivesignals/brscot/1985-cowlairs.pdf

 

the cowlairs end was resignalled in 1993 in conjunction with the 'cowlairs chord' going in, but queen st. isn't shown: http://www.s-r-s.org.uk/archivesignals/brscot/1993-cowlairs.pdf

More likely to be a ground mounted signal rather than a ground signal, a full head, with call on, but mounted on the ground rather than a post, probably had a small theatre on it to give platform routing information - the theatre could well have been a stencil if space was tight.

 

The drawing (1985) shows it as a ground mounted 2-aspect inverted signal (red to the top) with a call on and (probably) a stencil
