The Production Batches
Even before the locomotives supplied under the Pilot Scheme had been tested and evaluated, political and social pressures led to abandoning the slow and measured implementation which the engineers wished to follow, and orders for mass production were placed.
Ten of the Pilot Scheme locomotive Types were selected for further construction and the numbers multiplied with the total class members becoming:-
Type 4
D1-193 193 locomotives
D200-399 200 locomotives
D800-70 71 locomotives
Type 2
D5000-5299 + D7500-7677 478 locomotives
D5300- 5415 116 locomotives
D5500- 5699 + D5800-62 263 locomotives
D6100-57 58 locomotives
D6300-57 58 locomotives
Type 1
D8000-8199 + D8300-27 228 locomotives
D8200-43 44 locomotives
A second generation of diesel locomotives were designed and built as follows:-
English Electric Type 4, D400-49, 50 locomotives - Prototype DP2
These locomotives operated on the LMR where they replaced electric locomotives on passenger trains north of Crewe prior to the electrification from Weaver Junction to Glasgow. Introduced between 1967 and 1968.
BR Swindon 'Western' Type 4*, D1000-73, 74 locomotives
The Westerns were the ultimate production class of locomotive in the view of many enthusiasts and ran on the principle services of the WR. Introduced between 1961 and 1964.
Brush Type 4*, D1500-1999 + D1100-11, 512 locomotives
These locomotives became the Standard Type 4 and were used on all duties from express passenger to merry-go-round freight trains. They operated on all regions, but were not allocated to the SR sheds. Introduced between 1962 and 1968.
BRC&W Type 3*, D6500-97, 98 locomotives
This was the Standard Type 3 for the SR and the class operated all diesel services on the region, both passenger and freight. Introduced between 1960 and 1962.
English Electric Type 3*, D6700-6999 + D6600-8, 309 locomotives
These locomotives were the Standard Type 3 and operated on all regions, but were not allocated to the SR sheds. They were regarded as mixed-traffic. Introduced between 1960 and 1965.
Beyer Peacock Hymek Type 3*, D7000-7100, 101 locomotives
These 1700HP B-B diesel hydraulics were the mixed traffic Type 3's for the WR and proved a master of all duties. The body styling and imaginative colour scheme made them favourites with enthusiasts. Introduced between 1961 and 1964.
Clayton Type 1 *, D8500-8616, 117 locomotives
The Clayton Type 1 was designed with the benefit of experience gained from the three Pilot Scheme Type 1's, and should have provided an all-round Type 1 capable of satisfying the operating departments requirements. Introduced between 1962 and 1965. However, the design had several basic flaws which resulted in frequent returns to the manufacturer, and BR soon ordered an additional 100 EE Type 1's and withdrew the Claytons, some with operating lives of only 5 years.
English Electric Type 5 Deltic, D9000-21, 22 locomotives – Prototype DELTIC
The 22 Deltics replaced 55 steam locomotives on the former LNER main line from Kings Cross to Edinburgh, and were an instant success. As the permanent way was improved during the 1960's these 'racehorses' hauled expresses which were regularly timed at 100mph, and revolutionised the ECML passenger services. Introduced between 1961 and 1962.
The locomotive types marked * entered traffic in quantity straight from the drawing board and without the building of prototypes.
