Charles De Lano Hine,
Letters from an Old Railway Official to His Son…
“ What I am telling you holds good for a trainmaster, a yardmaster or whoever happens to be the senior representative present. Sometimes it is better to send out the trainmaster and stay in yourself to handle an already congested situation. Sometimes the trainmaster is at the wrong end of the line and you must go yourself. Common sense is a pretty safe guide as to one's course of action. The principle to be remembered is to avoid interference with the man on the ground. If it is a minor derailment which the conductor is handling, do not rattle him with messages, with requests for reports. ”
