One final comment on the need for caution and, above all, common sense at railway crossings.
The speed limit for freight trains passing through White Rock is 25 m.p.h. but even at that slow speed a mile-long freight train or a fully loaded coal train requires almost a mile to be brought to a full stop.
So even if an engineer sees people on the track, there is no way he could stop a train in time. Common sense, alas, is not very common.
