All others designated Special Trains, whether Passenger, Freight or Work.
Conductors, brakemen and switchmen must carry two detonating signals when on duty. REMEMBER THAT THIS IS A MATTER OF LIFE AND DEATH.
Full stop at all Diamonds & proceed 10 m.p.h., and Drawbridges & proceed 4 m.p.h.
Running shunts are strictly forbidden.
Comparison with more recent rule books will of course accent the major differences in signals etc. Red, green and white are now red, yellow and green.
White was replaced with green as the proceed signal because of incidents involving mistaken signal indications, some where a coloured lens fell out of a moving semaphore arm leaving just a bare white light. It also played a roll in the wreck that killed Frank Blaine when he momentarily thought the dim headlight of another locomotive was actually a clear signal.
Crossing signal is two long, one short, and one long; but until about 1930 is was two long and two short.
The bell cord was soon replaced by a small air line and the familiar "peeeep" whistle in the cab.
And of course two red flags on the front of an engine was replaced by two green flags to designate "sections following" with the last one displaying no signals. Two white flags now indicate an extra train for the train displaying these signals, not a following train.
Special Trains are now, of course, called Extras.
Some additional comment on old terms:
Public timetables often refer to Express trains. These should not be confused with trains carrying express (packages) but rather they referred to fast trains making a limited number of stops.
Accommodation, was another old term and it referred to local trains making all stops (or flag stops) and usually handling all types of head-end traffic, mail, milk, newspapers, express etc., thus "accommodating" everyone and everything!
