Charles Francis Adams, Notes on Railroad Accidents
“ On the London & North-Western there are more than sixty through down trains, taking no account of local trains, each day passing over the same line of tracks, among which are express trains which stop nowhere, way trains which stop everywhere, express-freight, way-freight, mineral trains and parcel trains. On the Midland road there are nearly twice as many similar trains on each track. On the Metropolitan railway the average interval is three and one-third minutes between trains. ”
