"Railway Archive" 19 has a number of postcard illustrations of G.W.R. stations in Devon. One, on Pg 79, illustrates Bickleigh station on the Yelverton branch. This was single line, but Bickleigh had a passing loop with up and down platforms on it. The view shows the two platforms and a small goods yard to the left.

It appears that there was a tandem turn out (ie three way) at the end of the loop - the left hand road served one platform, the right hand one the other platform and the centre road led to the yard on the left of the left hand platform, so it crossed over the left hand road (all rather difficult to describe).

Does anyone know of another photograph showing this curious arrangement, please? Presumably its purpose was to minimize the number of facing points.

Hi John,

I don't have another picture of that, but it was very common for a yard connection to cross to the opposite side of a loop to ensure a trailing connection into the passenger lines.

Here for example is Rubery on the Halesowen Railway:

There was a similar arrangement at Kirkcudbright station - in that case the lead was to the engine shed and turntable.  The OS map shows ir here

but you will have to use the "zoom in" and "pan" controls to see it clearly. I can't seem to get a URL which will show the appropriate enlarged view. :(

Many thanks for the link. I had forgotten what an excellent resource that site is. :)

Martin,

How did you get that size and level of definition?  I tried your version of the URL but could only get a JPEG file of 526 x 357 of the whole map which obviously would never zoom in to get the detail you have displayed.

[Edit]  Using the latest version of Firefox,  just installed yesterday.

Jim.

Martin,

With reference to the Kirkcudbright arrangement,  I think I remember reading that the arrangement avoided the provision of another facing point lock on the platform line which might have complicated the interlocking for the single line working.

Hi Jim,

??? I went to your original link. Right-clicked on the image and then Copy Image Location (in Firefox). (In IE select Properties to get the image URL.)

This is the result:

http://www.nls.uk/lizardtech/iserv/getimage?cat=Maps&item=74416965.sid&cp=0.5,0.5&lev=5&wid=700&hei=500

I then edited the parameters as follows:

lev=  is the zoom level. You can go from about minus 2 (zoom in) to 8 (zoom out). I set it at 2.
wid= is the width of the displayed image in pixels. I set it at 700.
hei= is the height of the displayed image in pixels. I set it at 1200 to get in all of the track to the turntable.

cp= is the centre-location for zooming. 0.5,0.5 is the centre of the original scan. I left that at 0.5,0.3686284813452444 which is where I had been clicking/panning on it. (It would have been better to have edited it down to 0.5,0.4 or whatever.)

Which gave the URL for the image which I posted. I don't understand where your 526 x 357 is coming from? :? Is Firefox scaling it to fit the window? If you click on it, it should resize to full size.

regards,

Martin.

Jim.

The GER had a similar arrangement somewhere, maybe Braintree, a photo featured in the GER Soc Journal, can't remember which one and they are packed up now prior to a forthcoming move.  If I remember the details correctly it was to save on a facing point lock.


Cheers for now,

John from Harrow, Middx

Martin,

I must have cocked up when piecing the URL together. :)   I now works fine,  and I always forget about that "Copy Source URL" facility in Firefox. :)

[Edit] - Yes - I managed to miss out the "=" sign after "cp" in your URL :)

Jim.

Hi Jim,

How did you manage that? Can't you just drag the mouse over the whole URL and press Ctrl-C?

Martin,

It's probably better just to ponder on the state of my mind at 6.30am after half a night's work.  :):):)

Hi John,

It's quite a common arrangement. But often the diamond is given a slip road to create a trailing crossover, so the original idea isn't so obvious. Like this:

trailing_slip.jpgtrailing_slip.jpg

A nice sunny day in the 1950s somewhere in mid-Wales I think. The first switch in the yard seems very close to the V-crossing on the slip. I'm sure there must be some catch/trap points on the left, and the switch behind the photographer will be rodded from the box for the same reason.

(Copied from a calendar ages ago, and I have now forgotten where, so © unknown -- anyone?)

regards,

Martin.

Hi Jim,

Mine's like that all the time nowadays. :) I've been racking my brains to remember the location of the pic I just posted. :(

Three Cock's Junction.

Also I know this has featured on the Forum before but I still think I need to build this one sometime.

Gents,

As a new user I have just come across this topic, but despite living just a few miles from Bickleigh I cannot supply a photo of the prototype although there is a shot in a book "the Branch", author Bernard Mills, which was published by the Plym Valley Railway group about twenty years ago. They have a web site which may be of help.

On a more general note whilst the last set of conversations were going on, myself and the rest of the East Somerset P W Gang spent a week re-timbering a similar crossover set up to that in the photos at Cranmore. This has a further complication in as much as a second siding connection crosses in the other direction leading to a second diamond on the siding approach intersection.

If I can work out how, I will attempt to attach a shot or two of the nearly completed work to this message. If not anyone is welcome to come to Somerset to view the resultant tangle

Gents,

 

Hopefully these should be the pictures mentioned in my last posting. Note also that the crossing on the "main line" was originally a single slip but was converted to a simple diamond by B R sometime in the distant past. They very helpfully left the displaced rail in the undergrowth but took away the cast replacing the specials with standard S1 chairs
