I noticed this book by Alastair McLean being the subject of a review in The Scots Magazine for March 2011.
"By late 1981, all the Deltics had gone, after two decades as Britain's fastest and most powerful locomotive. This unique class of 22 locomotives was powered by twin Napier Deltic engines, originally made for minesweepers." Deltics were a common sight from Kings Cross to Aberdeen.

Here is a small description from "The Deltic Preservation Society"
Does a Deltic sound different to any other diesel loco?
A Deltic sounds very different to any other locomotive. At idle, the phasing gears inside the engine can be heard as can the scavenger blower and the exhaust. The noise varies depending on where and how far you are standing in relation to the locomotive. The engine note is like a low, rumble of thunder.
An 18 cylinder Napier Deltic rail traction engine idles at 700 rpm (faster than most other diesels at full bore) and can run up to 1500 rpm. As the engine rev’s increase the Deltic engine also changes character. The rattling and vibration in the phasing gear changes frequency, and the engine note becomes a higher-pitched, very smooth drone. For this reason the locomotives are sometimes nick-named ‘Drones’ or ‘Lancaster Bombers’.
After hearing a Deltic engine, be it in a Class 55 or a naval craft, it is very difficult to mistake them for anything else.

Watch and listen to a "Deltic" at startup........turn up the sound :smile:
Napier Deltic class 55 55022 engine starts and departure Bury Bashers view.
Class 55 Deltic 55022 engine starts and departure from Bury, with the 14:00 service to Rawtenstall. 02/05/2010..... I must admit I was caught out and pleasantly surprised when both RSG's engines started ;-)
Napier overload!
On 20th September 2003, at Barrow Hill, Class 55 Deltic no. 55019 'Royal Highland Fusilier' erupts as she takes a small train + sister loco D9009 'Alycidon' out of the station. Sound level goes to overload!!!
