The railways of today have two faces; the new and the old. One is represented by reinforced concrete, electronics and high speed trains; the other by cast iron, semaphore signals and the steam locomotive. It was without doubt the steam locomotive that contributed most to the old face for she was not only proof of man's engineering skill, she also stimulated the imagination of people to such a degree that those who have ever watched her in earnest know that it is hard to find a machine more facinating and lively.
