Bradshaw’s Railway Companion:

COPP: “Just look up the trains in Bradshaw”: (George) Bradshaw’s Railway Companion, begun in 1839, were railway time tables (Britain had many competing railways companies) that were indispensible in confirming or refuting alibis and are mentioned several times in the Canon. The company also published guides and maps and even air travel guides. The last guide was printed in 1961.
