The NS 5000 was a series of steam locomotives of the Dutch Railways (NS), taken over from the British War Department.

The locomotives, with wheel arrangement 1'E (2-10-0), were built between 1943 and 1945 by the North British Locomotive Company in Glasgow for the British War Department to supply the British Army with supplies during their fight against the German army in mainland Western Europe. Their low axle load of 13.7 tons made them very suitable for running on makeshift or repaired railway lines.

A number of locomotives were used in the south of the Netherlands during the English occupation. Around October 1945 the locomotives were taken out of service and put into storage.

In order to get railway traffic going after the surrender of the German army in May 1945, these war locomotives were a welcome addition to the heavily reduced fleet of Dutch steam locomotives. At the beginning of 1946 it was decided that the NS would hire about sixty locomotives as NS 5001-5060 for pulling freight trains. Later this number was supplemented with an additional 43 locomotives so that the series NS 5001-5103 was created.

The NS soon lowered the steam pressure from 15.8 kg/cm² (225 PSI) to 12 kg/cm² (170 PSI) and made the chimneys longer to clear the smoke from the driver's view. These locomotives were withdrawn from service between 1948 and 1952.

The 1,000th British-built locomotive shipped to continental Europe was commemorated. This locomotive, with the name "Longmoor" has been preserved in the Dutch Railway Museum in Utrecht and has been brought back in the War Department condition with the number WD 73755.^[1][2]

Background[]

The NS 5000 1'E (WD 2-10-0) was based on the NS 4300 1'D (WD 2-8-0), and was designed to have interchangeable parts by R.A. Riddles. It had the same power output as the 1'D but a lighter axle load, making it suitable for secondary lines.^[3]

Design[]

These locomotives had a parallel boiler and round-topped firebox. While the 1'D (2-8-0) had a narrow firebox, the 1'E (2-10-0) had a wide firebox placed above the driving wheels. This arrangement was common in the United States (e.g. the USRA D (0-8-0)) but unusual in Britain, where wide fireboxes were usually used only where there was a trailing bogie, e.g. in 2'B1' (4-4-2) and 2'C1' (4-6-2) types. These were the first 1'E (2-10-0) locomotives to work in Great Britain, and the first major class of ten-coupled engines — they had been preceded by two E (0-10-0) locomotives; the Great Eastern Railway's Decapod and the Midland Railway's Lickey Banker. The 1'E (2-10-0) wheel arrangement was later used by Riddles when he designed the BR standard class 9F. This, too, had a wide firebox placed above the driving wheels.

Construction[]

Two batches were built by the North British Locomotive Company, the first batch of 100 introduced in 1943/1944 and the second batch of 50 in 1945. Their WD Nos were 3650–3749 (later 73650–73749), and 73750–73799.

20 of the first batch were sent to the Middle East. During running-in they worked in Britain, but their length made them unsuitable. Most saw service with the British Army in France after D-Day.

Preservation[]

NS 5085 (WD 73755) survives in the Dutch Railway Museum (Nederlands Spoorwegmuseum) in Utrecht. It carries the nameplate Longmoor, after the Royal Engineer's base at Longmoor, with the coat of arms of the Royal Engineers above. NS 5085 is alone in preservation in the netherlands. however there are more locomotives of the class WD Austerity 2-10-0 still around.^[3][2]
