Tier 1—These standards apply to locomotives and locomotive engines originally manufactured from 2002 through 2004.

Why train engines are not turned off?

Trains, being large and heavy, need the optimal brake line pressure for its efficient stopping. For obvious reasons, loco pilots never compromise on brake line pressure. Another reason for not turning off diesel train engines, lies in the engine itself. A train’s diesel engine is a large unit, with around 16 cylinders.

Is Class 37 a Deltic?

Quoting from RS Carter ”The traction motors (Class 37) are identical and interchangeable with the traction motors fitted to the production “Deltics”. The Deltics were rated at 100mph whilst the Class 37s were only rated for 90mph.

How many Deltics are preserved?

The 22 locomotives were named either after racehorses or regiments, both naming themes popular in steam days, and six were preserved in working order as well as two cabs and the pre-production prototype at the National Railway Museum.

Class 31s were used as regular motive power briefly on the Cotswold Line after the withdrawal of the Hymeks, but were quickly removed due their low power. 31405 was doing commendably well on this occasion, passing Chilson only 15 minutes down on the schedule.

When did diesel locomotives come to the UK?

In the 1950’s the British Rail board at the time decided they needed to replace steam traction in the UK and to do this they needed to build large numbers of Diesel Locomotives and amongst the locos that were to be built was the Brush (Loughborough Locomotive Works) built class 30 later to be reclassified class 31 Locomotives.
