Wonders of World Engineering

Part 10


Part 10 of Wonders of World Engineering was published on Tuesday 4th May 1937, price 7d.


Part 10 includes a colour plate showing A Streamlined Giant of the Canadian National Railways illustrating the article on Canada’s Streamlined Engines.




The Cover


This week’s cover shows the unique Barton Aqueduct, which carries the Bridgewater Canal across the Manchester Ship Canal on a swing bridge. How this remarkable arrangement works is described in the chapter on the Manchester Ship Canal beginning this week, on page 314.


The Manchester Ship Canal is also described in part 26 of Shipping Wonders of the World.

JamJames Nasmythes Nasmyth


A brilliant and successful engineer, Nasmyth contributed much to the development of engineering practice, and was the inventor of the steam hammer. This appliance revolutionized the methods of forging and made possible the making of forgings of a size previously thought impracticable.




This is the fourth article in the series Makers of Engineering History.

Conquest of the Desert (Part 2)


The story of irrigation in the Sudan by the building of the Sennar Dam across the Blue Nile. This chapter is by Harold Shepstone and is concluded from part 9. It is the fourth article in the series on Triumphs of Irrigation.

(Pages 293-295)


You can read an account of the opening of the dam, in March 1926, here.



A Streamlined Giant


A STREAMLINED GIANT. No. 6401, of the Canadian National Railways, is one of a new class of single-expansion passenger express locomotives which appeared in 1936. The engine has eight coupled wheels and leading and trailing bogies, giving her the 4-8-4 wheel arrangement. The two cylinders have a diameter of 24 in and a stroke of 30in. The driving wheels are of 6 ft 5 in diameter. The diameter of the boiler barrle tapers from 7 ft 2 in to 6 ft 6 in. The working pressure is 275 lb per square inch. Tractive effort at 85 per cent boiler pressure is 52,450 lb. The grate area is 74 square feet; mechanical firing is provided. The tender is carried on twelve wheels: its capacity is 11,700 gallons of water and 20 tons of coal. The total weight of engine and tender, in working order, is 296 tons.

Romance of the Safe Deposit


The design of vaults and strong rooms to withstand earthquakes, fire, explosion, or the scientific methods of burglary has demanded all the skill and ingenuity of the engineer. This chapter describes the evolution and design of the safe deposit. The article is by Harold Shepstone.

Handling 2,000,000 Tons of Coal


Every year some two million tons of coal are discharged from colliers at Beckton Gasworks, London, and 250,000 tons are kept in reserve. The largest plant of its kind in the world handles, grades, crushes and delivers the coal to coke ovens and retorts. The plant deals also with the coke that is formed from the coal. This chapter is by Sidney Howard.

This article complements the one on Gas Production which appeared in part 2, whilst you can read about the Beckton Gas Works Railway in Railway Wonders of the World.



Canada’s Streamlined Engines


To meet the constantly increasing demands for higher speeds and heavier trainloads, the Canadian National Railways have recently built five streamlined locomotives of enormous size. No. 6400 of the CNR and others of her class weigh, with tender, in working order, 296 tons each. Written by Cecil J Allen, this chapter describes locomotive No. 6400 and her sisters, which differ widely from other engines on the Canadian National system. This article is the second in the series on the Marvels of Modern Transport.

Britain’s Biggest Ship Canal (Part 1)


By its conversion of a great inland city into a seaport the Manchester Ship Canal is an outstanding example of the influence of the engineer’s work on the lives of others. After innumerable difficulties and destructive floods the canal was opened in 1894.

 This chapter is by David Masters and the article is concluded in part 11.

(Pages 314-320)


There is another article on the Manchester Ship Canal in part 26 of Shipping Wonders of the World, whilst the cover of part 28 shows the SS Diplomat at Eastham on the canal.
