One of my first rides behind steam in Scotland was a run from Edinburgh to Aberdeen and back behind 60009 'Union of South Africa'. The train started diesel hauled from Newcastle and I recall it was a very long day!
Near the end of the return journey 60009 is heard passing Inverkeithing. Beyond is the steep climb up onto the Forth Bridge and the A4 makes some fine sounds during the ascent.
By this time it was dark and the rain of cinders from the chimney had to be seen to be believed. It is just as well that there are no thatched roofs in North Queensferry!
