I saw this link posted on another group:
The first part is mainly road traffic - it's fun trying to identify all the cars and trucks, many of which have recently been reissued in model form. Most of the clips are of assorted passenger and goods trains and light engines going about their daily business. The locos looked pretty scruffy, apart from an immaculate "Mallard" heading an Ian Allan Locospotters Special. There's the odd shot of a diseasel, but the vast majority were authentic smoke-belching, steam-spitting beasts. King's Cross station had quite a different atmosphere in those days! And, of course, at the platform ends there was the inevitable gaggle of young trainspotters.
