What a valuable collection this is!
There are more than 1500 different signal box diagrams in this collection variously in the form used for display in the signal boxes, sketch diagrams and office copy versions. A few 'route maps' have been included which were produced for planning purposes. These 'cancelled negative' diagrams were microfilmed by British Railways who then disposed of the originals; the diagrams in this collection have been scanned from the microfilms.
The diagrams were the S&T master ones that were updated whenever changes were made. A consequence of this is that each diagram is in the final state reached although sometimes erased elements can be made out.
The diagrams are provided in PDF format and can be read by pretty well any computer, tablet or mobile phone. It is possible to print the PDF files but be aware that the printed size is suitable for display over the block shelf of a mechanical signal box or on a large map table. A large format printer will be needed for this. To print on most domestic printers you will need to scale to fit the page size you have available.
Please note that these disks are produced to order.
