Signalling Notices Digital Archive

Most documents in the digital archive are in PDF format. However, some larger files may be in JPG, PDF, PNG or TIF format. The files are supplied strictly “As Is”. The entries in each list will make it clear what is available to download and what is only available by other means.

Please do not pass copies of the files around, instead ask interested persons to contact the Society to obtain their own copy. In terms of copyright, British Railways (Residuary) Ltd confirmed to the Society that it was 'not interested' in historical documents that had outlived their operational usefulness and this line seems to have been followed by Railtrack and now Network Rail, as may be evidenced by the quantity of modern material that has entered the public domain through eBay and other auction houses and second hand bookstalls. Similar advice has been received from London Underground in respect of material obtained lawfully from their staff or is already in the public domain.

If there is a download link in the left hand column, the notice concerned may be downloaded free of charge but bear in mind that the file may not contain all the items listed. Otherwise, if there is a “Members' Download” entry present in the item description, then Members (only) may download a copy of the file. If both links are present then Members will sometimes find additional information or a cleaner copy is available by using the “Members' Download” link.

Members will find the information needed to Log-in in the Announcements section of the Society's Forum. Be aware that the passwords will change from time to time and without warning. Non-members will need to JOIN the SRS first and then register for the Forum.

Notices flagged with an asterisk (*) are not included in the free download file.
