The sound of that Napier engine rumbling before visiting Deltic 'Alycidon' departs Kidderminster! It's running all weekend at the Autumn Diesel Bash. Get tickets: https://www.svr.co.uk/events/autumn-diesel-bash/ | Severn Valley Railway

This video demonstrates the engine sounds from 4 different classes of British Rail diesel locomotive. They may look visually (slightly) similar but they each have a characteristically different engine sound. The class 37 and class 40 have different types of engines, but both were built by the English Electric Company. The class 44 has a Sulzer engine, and the class 55 has a Napier Deltic engine. So there you go! #trains #diesellocomotive #britishrailways #railways #trainspotting #heritagerailway

The complex beast which is a Napier Deltic engine. A model of how the engine works. Plus I have added the sound of a real class 55 Deltic engine running, just for added ambience! #trains #diesellocomotive #britishrailways #railways #trainspotting #heritagerailway #deltic #class55 | Adrian Watson

A brief ride behind a class 55 Deltic locomotive (55009). Running on a single Napier Deltic power unit, which is more than enough power for this gentle incline. A joyful plume of clag rising from this majestic locomotive. Somewhere, Greta gently weeps. The Deltic Preservation Society The Keighley and Worth Valley Railway | Adrian Watson
