An Operating Problem.

Railwaymen the world over dearly love an operating problem. Here is a little poser which aroused no small discussion in a certain Home railway mess-room the other day:—A. and B. a[gap — reason: illegible] two railway stations, a seven hours' journey apart, and with a double track (i.e., an Up and a Down line), between. At every hour a train leaves A for B, and another leaves B for A. All the trains travel at the same speed. Supposing you were in one of these trains going from A to B, how many trains would you pass en route?

Simple though this problem really is, quite a number of experienced railwaymen have proved incapable of offering a correct solution. How many readers of the “New Zealand Railways Magazine,” one wonders, can supply the answer. Next month, by courtesy of the Editor, the solution will appear in these pages.
