Finally, single line to Courthouse Junction SBD 176 kb, courtesy Industrialogical Associates Collection. 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. Ecclesfield East, probably final layout (1.2 Mb). The GCR Barnsley-Sheffield line was severed in 1966, in connection with the building of the M1 motorway, and Ecclesfield became the northern end of the line from Sheffield, serving Smithywood coking works and Smithywood Colliery. This diagram shows the stageworks and some of the original layout (2.2 Mb). 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. Elsham SBD, 1/2/1967, 434 kB, courtesy Industrialogical Associates Collection.

Upon electrification, Sheffield No 3 acquired a control panel to operate the colour light signals - here is the control panel, courtesy of Greg Nicholson (1261 kB). Here is a contrast enhanced version, made in an attempt to read the text which has been rubbed out (1923 kB) 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.

Woodhead (SBD, 1954, 404 kb) Also available is the Woodhead block shelf layout diagram (2277 kb). For both Woodhead and Dunford West, photographic evidence survives showing that the main line block instruments were of the Tyer 'black box' variety. But I've never seen a photograph of the Woodhead goods line block; was it really an LNWR permissive as shown on this drawing? Both diagrams courtesy of Simon Foster.

Harwich SBD, no date, 340 kB, courtesy Industrialogical Associates Collection. There is no date on this diagram, but Peter Dobson kindly emailed me with the following comment: 'With the single line bi-directional nature of the 'bottom' track it most likely dates from after the electrification of the ex GER main line etc from Colchester on to Norwich. It is always possible that it dates from a bit earlier but is definitely post steam age.' Hethersett SBD, no date, 137 kB, courtesy Industrialogical Associates Collection.

Ely Station North SBD, 23-1-1968, 608 kB, courtesy Industrialogical Associates Collection. Great Northern Railway Ardsley Station SBD, probably late 1960's (1446 kb). I like this diagram - I was brought up in Morley, and it is the only diagram I have from within the old Borough of Morley! 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. Bentley Crossing SBD, no date, 422 kB, courtesy Industrialogical Associates Collection. Doncaster 'C' SBD, no date, 949 kB, courtesy Industrialogical Associates Collection. East Holmes SBD, no date, shows swing bridge, 121 kB, courtesy Industrialogical Associates Collection. Finsbury Park No 3 SBD, no date, 891 kB, courtesy Industrialogical Associates Collection. Firsby Station SBD, no date, 676 kB, courtesy Industrialogical Associates Collection. 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, 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.

Lancashire and Yorkshire Railway Barnsley Exchange Junction - two diagrams, no dates, but probably 1950's and 1960's: earlier diagram (545 kB) - shows single platform and engine shed. The engine shed was demolished to make way for a second platform in 1960 - as shown in this later diagram (faded office copy, contrast stretched, 697 kB). Birkdale, copy drawn by Harry Gardner (255 kb) Bradford Exchange SBD, BR diagram, no date, 876 kb. The old Bradford Exchange Station consisted of two, unconnected halves (one LYR, the other GNR), controlled by one signal box. This is the LYR half. Connection between the LYR and GNR lines was provided at Mill Lane Junction, the next block post to the south. 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. Brierfield, copy drawn by Harry Gardner, about 1985, from the diagram in the box (292 kb) Brindle Heath Junction, copy drawn by Harry Gardner Bullfield West, copy drawn by Harry Gardner from an S+T print (306 kb).

This diagram corresponds to the replacement frame installed Sunday-Monday 3-4 October 1937, and removed in the mid 1960's (information provided by Tony Graham). The diagram was badly torn when I received it and was in need of some digital restoration... I subsequently received an email from M Shaw, who has restored the diagram and - as you can see here - done an excellent job (997 kB). Low Moor No 4 SBD, 1957, 358 kb.

Number 10 points were removed about this date, the line from Number 9 points having become a private siding. Some time later a board marked 'Stop and Await Instructions' was provided on this siding, 60 feet in rear of the fouling point (information from Tony Graham). Some more information about Canning Street can be found here.

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.
