signal box diagrams

The diagrams presented here are a mixture of actual box diagrams or office copies of box diagrams (denoted SBD) and working sketches (denoted WS). They are arranged by company which provided the railway line, not the diagram - most of the diagrams are in fact from the British Railways era.

Some of these diagrams are in my own collection; others have been loaned or scanned by other people.
The late Andy Rush kindly allowed me to display here diagrams from the Industrialogical Associates Collection. These diagrams were scanned, and in some cases, coloured by him.
Harry Gardner, a former BR signalman, has kindly allowed me to display here some of his hand drawn copies of signal box diagrams.
Thanks are also due to Simon Foster for help in scanning some of my own diagrams, and providing scanned copies of others.
Additions to this page will be made from time to time, as circumstances - and my scanning inclinations! - permit.
If you find these diagrams of interest, you may also wish to visit Brian Begg-Robertson's Sectional Appendix site.
Filenames are generally of the form place_q65.jpg, where the q65 (or other value) refers to the compression of the jpg file. In some cases a higher quality file is available by entering _q95 or in a very few cases _q100.

And here are two Dodworth diagrams, apparently from a scheme which never actually happened (Dodworth never worked single line to Courthouse Junction): single line to Courthouse Junction SBD 176 kb, courtesy Industrialogical Associates Collection; also sketch for single line to Courthouse Junction, including interlocking, (apparently dated 1967).
Dunford West (SBD, 381 kb) Shows arrangements for single line working in Woodhead tunnel, but does not show station yard, despite being dated March 1954 (compare with 'Woodhead - The Electric Railway' by E M Johnson, page 92). The edges of the holes in my diagram show evidence of having being 'chewed' - suggesting it was affixed over the original diagram shown in Johnson's book.
Here is the Dunford West block shelf layout diagram (831 kb, courtesy of Simon Foster). The photograph referred to above shows that the actual block shelf did not exactly match the diagram; although both main line blocks were Tyer 'black boxes', the goods line block to Dunford East was a standard GCR non-pegger, and the goods line block bell was of LNWR, not GCR, origin.

Elsecar Junction. No date, but probably the diagram prepared for the signalling alterations made about 1950, in connection with electrification. Shown in two sections: Elsecar Junction left (718 kb) and Elsecar Junction right (782 kb).
This diagram was made available through the courtesy of G Nicholson. It is drawn in a slightly different style to later diagrams - note the route indicators on the colour light signals, where the each of the five white lights is shown!
Subsequently, more track circuits were added and the line to the west reduced from four track to two track. The final layout controlled from the power frame is shown on this layout plan (836 kB) - note the footnotes at the bottom which show the dates when various changes were made. Finally (for the time being!), here is the block shelf layout diagram (311 kB). These last two diagrams are from the book of wiring diagrams for Elsecar Junction - the diagrams all bear 1950 dates, with the exceptions of a a few more recent ones. I hope to add more information about Elsecar Junction in due course.

Sheffield Victoria No 4 diagram for Nunnery Junction. Nunnery Junction was formed in the 1960's when a new connection was made between the ex-GCR and ex-MR routes in Sheffield; it was controlled by a switch panel in Sheffield No 4 box. This diagram is marked (on the back) 'diagram for switch panel', but oddly lacks any track circuit indications. Otherwise, it is drawn in typical BR(ER) style of the period. Here is a photograph (271 kB) of the interior of Sheffield No 4, courtesy of Michael Kaye. It was taken in 1985, just before closure; you can see the frame is out of use, and the only trackwork still controlled from No 4 is the Sheffield (Midland) to Woodburn Junction link at Nunnery Junction. A higher quality version can be found here here (827 kB).

Great Northern Railway
Ardsley Station SBD, probably late 1960's (1446 kb). It's probably the last diagram before closure: The sidings and Ardsley North have gone, as has the junction with the Bradford line. Although this line still survives on the diagram, it has been redrawn as a siding. By this time, the connection with the main Leeds-Wakefield line was via the sidings at Lofthouse North. Notice the automatic signals between Ardsley and Leeds: these are labelled D (on the down line) or U (up line), with the mileage. I presume signal 27 is drawn incorrectly, and really is capable of displaying a stop aspect. A few years later I bought this: Ardsley Station, 1968, actual signal box diagram. This came with an overlay for the Morley branch, which had been removed and I have done some (digital) restoration (1115 kb). Here is the diagram with the overlay in place .

The Great Northern Railway once had an extensive system of lines in the West Riding, of which only the direct route between Doncaster - Wakefield - Leeds - Bradford now survives. A good guide to closed lines in this area can be found at the Lost Railways of West Yorkshire website. Just east of Bradford at Laisterdyke lay a complex set of junctions, the connections with the main Leeds-Bradford line being controlled by Laisterdyke East and West:
Hammerton Street SBD, 1953, 821 kB,
Hammerton Street SBD, 1970, 653 kB,
Horton Park Junction GNR SBD, dated 1902.
Laisterdyke West SBD, 1960's (1209 kb). To the west (right) the diagram shows eight tracks: four (main lines, down goods and a siding) run to Hammerton Street. The 1960 Sectional Appendix shows that the siding was originally the up goods, and ran as far as Laisterdyke East. Another pair of lines run towards Halifax, on a line which avoided Bradford; the next block post in this direction was Hall Lane. There are also connections to Planetrees Goods Yard. To the east (left) lay Laisterdyke East, where trains ran straight on towards Leeds, or turned south for a variety of routes: Leeds via Pudsey Greenside; Wakefield via Morley Top, or Wakefield via Dewsbury and Osset. The gradient profile is impressive, with the summit between East and West signal boxes at Laisterdyke.
Laisterdyke East SBD, about 1970 (476 kb). This seems to be a later diagram than Laisterdyke West (above): the sidings at the bottom of the diagram are all that remain of the line to Dudley Hill. The main line to Leeds is shown with modern track circuit block signalling, but in fact the 1960 Sectional Appendix shows that 'Automatic and Semi-Automatic Signals' existed between Laisterdyke East and Stanningley by that date. 'Railway Memories - No 4 - Bradford' compiled by Alan Whitaker and Brian Myland includes a photograph of the signal at Duckett's Crossing, which was of GNR somersault pattern with an automatic replacement mechanism. I had some fun 'dating' this diagram: a photograph by M A King dated 20 Sept 1969 shows the Dudley Hill line still connected to the main line; but Laisterdyke East had closed by October 1972 as it does not appear in the North Eastern Region Sectional Appendix of that date.

The diagram also shows the gradient profile from Milner Royd (the junction with the LYR main line near Sowerby Bridge) to Bradford - notice the steep drop into Exchange. A DMU ran out of control here in 1964, with fatal consequences.

Latchford (SBD, original faded, contrast enhanced, final layout). Although the final layout was rather minimal, the gradient profile is of interest: the railway through Latchford was re-routed in the 1893 in connection with the opening of the Manchester Ship Canal - note the 1 in 135 gradients on either side of the bridge over the canal. 1058 kb

Middlestown Junction SBD, 1967, 286 kb. Probably the final diagram before closure - it is marked 1967 and the box closed in 1968. There was originally a line to Dewsbury Goods, which carried 'straight on' between the up and down main lines (in this diagram), and the down main passed underneath this. The lines at the left hand end of the diagram originally went to Thornhill Midland Juncion, but here are controlled by the then new power box at Healey Mills.

Trent PSB - not a Midland box, but certainly Midland Railway territory! These images are made from a diagram of the panel when new. I have split it into six sections. These are large files - each between 3 and 4 Mb:
Trent part 1 - fringe to Chesterfield, Avenue Sidings, Clay Cross
Trent part 2 - Erewash Valley line, Blackwell East Junction
Trent part 3 - fringe from Netherfield, Nottingham Station; fringe from Lincoln Street; Radford Junction; Erewash Valley line including Pye Bridge Junction
Trent part 4 - Trowell, Radford, Mansfield and Lenton Junctions; Stanton Gate, Stapleford and Sandiacre,
Trent part 5 - Stapleford and Sandiacre, Toton, Trent Junctions
Trent part 6 - Trent Junctions, fringes to Derby and Loughborough

It is stamped 'North London Railway Superintendent 25 Sep 1907', and also bears the name 'H E Short'. The document comprises a bound collection of photographic prints - each about 11x5 inches - which appear to be copies of the actual box diagrams, and covers the whole system.

Bidston Dee Junction A few years ago I bought the original illuminated diagram from this (LMS) box. Here is the diagram as I obtained it: image 1, image 2, image 3, image 4.
This turned out to be a later overlay, on top of an earlier LMS 'white on black' style diagram. Here is the earlier diagram: image 1, image 2, image 3, image 4. Files about 1MB each.
