The "1900 British and Colonial Points and Crossings Drawings" are 42 plates from the 1900 International Railway Congress report, Worthington_1900, by W B Worthington, on "British Railways Points and Crossings". This was Report 2 for Section 1 Question III of the 1900 International Railway Congress. The drawings show the points (now usually termed switches), crossings and rail sections used by a number of British and Colonial railways.
For an explanation of the IRC see IRC_article.
Information from these drawings was published in the article, Bate_1999, "Pre-Grouping Points and Crossings" by Ernest M Bate, in volume 16 no.10, pp.405-7, of the HMRS Journal, April-June 1999. When that article was written, the source of the drawings was unknown and the date was estimated as circa 1905, but they are now known to be 1900.
The drawings accompany a long written report, Worthington_1900 (Details of report), which analyses how points and crossings were designed in 1900, when every company had their own design for all parts of the permanent way, including the rails, joints, points and crossings. Plate 33 summarises how check rails and wing rails were commonly designed and plates 34 to 37 show possible designs for junctions. oldpway currently only has a full copy of the French language version of the report and a part copy of the English language version.
The drawings on oldpway are high resolution (600 dpi) scans made from the published IRC report (French version). Plates 13 and 14 (for the GWR) had a strip missing due to the book binding. This strip has been recreated from photos of a different set of the same drawings that in 1974 were kept in the Permanent Way Drawing Office of the British Railways Eastern Region Chief Civil Engineer, in Hudson House, York.
The drawings mostly give details of points (now usually termed switches), crossings, diamond crossings, check rails, rail sections and crossover junctions.
These drawings are free to copy and use for any purpose, but please credit oldpway as the source.
The files are pdf format. When viewed at 100% size, they are the size of the published drawings. The overall sizes vary between 12" wide by 10" high and 28½" wide by 10" high. The drawings include very small details that are best viewed at 400% size. The scans are black and white lossless high resolution (600 dpi) so can be enlarged to 800% before pixels become obvious. If any details are unclear at high resolution please contact oldpway so the original drawings and greyscale scans can be examined.
Prints scaled to fit A4 are mostly usable, but A3 is better, and larger prints or zoomed in screen viewing are needed to read small details and dimensions. All plates have had borders added, which are marked with an inch scale so that the original size can be seen on enlarged or reduced prints. The size of the border is printed at the bottom right corner and the oldpway file name is printed at the bottom left corner.
The following table is a duplicate of the list on the oldpway drawings page. It details all the drawings, gives links to view them on-line, and includes the rail weights in lbs per yard. The page numbers, III/153 to III/192, are the page numbers in the French version of the 1900 IRC Proceedings. III indicates that this concerns Question III that was considered at the 1900 Congress.
