I was probably only about nine or ten when ITV’s investigative journalism flagship “World in Action” did a program about trains. The particular issue concerned a spate of derailments involving short wheelbase wagons, including a reconstruction the derailment and fatal collision at Roade in 1969 using 00-scale models.

For a small boy interested in trains, it was obviously fascinating stuff. But it was the theme music that stuck with me; both the dramatic opening theme, and the slower, more melancholy closing credits music, both of which are included in the above clip.

There’s something about those descending minor-key runs in the distinctive tone of the Hammond organ, both signficant elements of progressive rock’s musical palette. Not that I was aware of the existence of Yes, ELP or King Crimson at the time, that was something I wasn’t to discover until several years later.
