Crieff signalling alterations

Post by Bill_Gensheet » Tue Jun 25, 2019 11:13 pm

I have been wandering about looking for some 'after' photos of the remains around Crieff to compare to the published ones, and noted the following regarding changes to signalling at Crieff over the years when checking back to published images.
Is there a more recent diagram available for Crieff than the 1893 one ?
At a guess any major changes were in 1932 with the closure of West box.


The Crieff East box diagram (dated 1893) published in 'Strathearn' book and the CD with 'Signalling' shows splitting distants for station vs goods yard and worked by levers 24/29/44/52.
An image in 'Streathearn' (plate3.30 page 72) of Pittenzie (with a platform, so after 1958) shows very tall single posts and one signal per line - no sign of the former brackets .
Were they now fixed ?, I cannot make out any balance weights in the image.
Are these even the original posts, if not someone went to a length to remove the brackets


Also images in 'Streathearn' (plates 5.1, 5.2 and 10.2) of the oft published view from Duchlage bridge of the signal box show signals not on the 1893 diagram, a main and a sub into the platform.

I also came across several images on the public Crieff facebook group ....

The Pittenzie LC 'non-splitting parallel distants' reduced to one arm in 1966. Compare to 'Signalling' book page 16

A further change from 1893:

Sig 36 acquired a bracket for the Madderty/Perth line

1964 image

It is also probably present in the 1948 image.
Also only one disc to exit the yard - there was one for each route (Madderty, Muthill) in 1893
The headshunt looks to remain a flap in 1948, would not be not visible in the 1964 image anyway.

It does raise the question of the application of sig36 had in the original 1893 plan.
Thoughts ?

Hi Gary,

Here is one diagram that may be of interest. I have a couple of others, one including details at Pittenzie & Pittentian, but they are two big for site. Ping me your email and I'll send direct.

kind regards,

Robert

Hi Robert,

Many thanks, PM sent.

That looks to be a very comprehensive set of shunting moves that were fully signaled. The 1893 arrangement was, by contrast, very short of those.

I do wonder how often the 1893 distants were actually used in their service life, and why anyone would have set up a distant to read onto a subsidiary into a dead end goods yard.

regards
Bill
