Railway Working, Diagram of Working Time Table of Great Northern Railway from April 1874, drawn by R. Price Williams and printed by lithography by Thomas Keith, 400 King street, Covent Garden. There is a 24-hour table at top and bottom (each hour divided into 10-minute units), and a division of express and ordinary passenger and freight trains in the legend at bottom. This lovely image of time and lines measures 7x30", and is an illustrative chart in Minutes of Proceedings of the Institution of Civil Engineers...volume XXXVIII, Session 1873-4, part II, edited by James Forrest, and printed in London by the Institution in 1874. Such was the way a country was run.
And a detail:
I found an explanation of this diagram in Engineering, September 24, 1875, page 249:
"This represents a portion namely between the hours 9 am and 2 pm of a diagrammatic time table for April 1874 of that part of the Great Northern Railway lies between King's Cross and Peterborough the between the vertical lines indicate time, those between horizontal lines the distance between the stations while diagonal lines show the passage of the trains and by different colours the nature the trains. At 9 o clock will be seen a train leaves King's Cross and arrives Peterborough at 10.40. The diagonal representing train is not quite continuous there is a small part drawn upon the Hitchin station line this shows the 9 o clock train reaches Hitchin at 9.45 and that it there for about three minutes. At 9.5 an train leaves King's Cross but goes no further than Green while at 9.8 another train leaves Cross and proceeds as far as Hatfield. At 9 10 a coal leaves King's Cross and reaches Peterborough at 1.20. 10 o clock an express train leaves King's Cross Peterborough at 11.30 and at 10.10 another express King's Cross reaching Peterborough at 11.45.
