AN ENGLISH RAILWAY.

This is done, as before stated, at the monthly meetings of the Officers' Conference, held during the third week of every month, and between that time and the end of the month the time-tables have to be revised and reprinted. No one who has ever glanced with an intelligent eye at the time-table of a great railway will be surprised to learn that this operation is one of the most complicated nature, and involving great labour and considerable skill. This will be apparent if it be borne in mind that, supposing, for instance, a train running from London to Scotland is altered in its timing ever so slightly, it involves the necessity of altering all the trains running on branch lines in connection with it, and many other trains which are affected by it A train service is, in fact, like a house of cards; if the bottom card be interfered with, the whole edifice is disarranged, and has to be built up afresh.
