|Engine:||2 Napier Deltic D18-25 diesels|
|Power:||3, 300 hp (2, 460 kW)|
Deltic was designed with the export market as well as home in mind and was given a "North American" appearance complete with large headlight and speed whiskers. When it was built Deltic was the most powerful diesel-electric locomotive in the world and it showed its performance on the London Midland and Eastern Regions  though had trouble with its loading gauge on parts of the East Coast Main Line. In the end the Deltic was ordered for production for the ECML in the form of the rather more British looking (and slightly slimmer) Class 55.
Deltic itself was preserved, being withdrawn from service in 1961. It was first displayed at London's Science Museum before moving to NRM Shildon in the last few years.
|Deltic now resides at NRM Shildon|
|Deltic remained privately owned and never had a BR running number|
|Note the large headlight and US appearance|
