Earl of Airlie was an 1833 steam locomotive designed and built by J and C Carmichael for the 4ft 6in gauge Dundee and Newtyle Railway, with a 0-2-4 wheel arrangement and a tender. It was the first steam passenger locomotive in Scotland and the first locomotive in the United Kingdom to have a bogie.
A second locomotive, of the same design, Lord Wharncliffe was completed shortly after Earl of Airlie. A third 0-2-4, Trotter, was provided by James Stirling & Co. in 1834, to a similar but sightly smaller design.
No other locomotives ever used the 0-2-4 arrangement.
The first railway locomotive to run in Scotland, The Duke , was introduced on the Kilmarnock and Troon Railway in 1817 or early 1818, to haul coal. [1] It was not a success.
The first locomotive in the world with a bogie, invented by John B. Jervis was Experiment (later renamed Brother Jonathan), a 4-2-0 design for the Mohawk and Hudson Railroad in the United States, in 1832.
The Dundee and Newtyle Railway opened in part in December 1831, and in full on 3 April 1832. [2] It was built to 4 ft 6 in (1,372 mm) and converted to 1,435 mm (4 ft 8+1⁄2 in) in 1849, having been leased to the Dundee and Perth Railway in 1846. [3] The Dundee and Perth Railway was in turn absorbed by the Scottish Central Railway in 1863. [4]
Earl of Airlie had an 0-2-4 (Whyte notation) wheel arrangement, meaning that it had no leading wheels, two powered driving wheels on one axle, and four trailing wheels on two axles. [5] [6] These latter pair of axles were on the bogie. [7] This was the first use of a bogie on a locomotive in the United Kingdom. [7] The driving wheels were 5 feet 4 inches (163 cm) in diameter, [lower-alpha 1] the bogie wheels 3 feet (91 cm). [5] [7] It used two vertical, single-acting cylinders of 11 by 18 inches (28 by 46 cm), one on each side of the boiler, mounted on top of the outside frames and driving the front wheels through bell cranks. [5] [7] Steam was provided by a fire-tube boiler at a working pressure of 50 pounds per square inch (340 kPa). [5] [7]
The locomotive weighed 9 long tons 10 cwt (21,300 lb or 9.7 t) and cost £700 (equivalent to £70,676in 2021) to build. [5] It was delivered from its maker, J and C Carmichael, on 22 September 1833, [5] along with a separate tender comprising a wagon with a water-barrel affixed, costing £30. [5]
Lord Wharncliffe, also made by J and C Carmichael, differed in having cylinders of 11.25 by 18 inches (28.6 by 45.7 cm). [5] It was delivered on 25 September 1833. [5]
A third locomotive, Trotter, was delivered to the Dundee and Newtyle Railway by James Stirling and Co. on 3 March 1834 and had driving wheels of 4 feet 6 inches (137 cm), though these were subsequently changed to 4 feet 8 inches (142 cm). [5] It weighed 7 long tons 3 cwt 2 qr (16,070 lb or 7.29 t). [5]
The Earl of Airlie at the time of the locomotive's introduction was David Ogilvy (1785–1849), the 9th Earl, who had succeeded to the title in 1819. Lord Wharncliffe was James Stuart-Wortley (1776–1845), the 1st Baron Wharncliffe. Both men were directors of the railway company, as well as being landowners in the area through which the line ran. [5]
The locomotives were numbered by the Dundee and Newtyle Railway as No. 1, No. 2 and No. 3, in order of delivery. [5] The first two were renumbered No. 10 and No. 11 respectively by the Dundee and Perth Railway in 1850. [8]
Earl of Airlie and Lord Wharncliffe were converted to run on standard gauge when the line was converted in 1849 (Trotter was scraped), under the auspices of the Dundee and Perth Railway. [8]
The two regauged locomotives operated until 1854. [lower-alpha 2] After being taken out of service, Earl of Airlie was used as a stationary engine, pumping water at Errol railway station. [8] [9] Lord Wharncliffe was used for similar purposes at the company's workshop at Seabraes, Dundee. [8]
Around a decade later, Alexander Allan, who became locomotive superintendent of the Scottish Central Railway in 1863, recognised its significance of Earl of Airlie. [8] [10] He had it removed, cleaned, cosmetically restored (albeit with the wrong type of buffers; sprung, instead of horse-hair filled), painted, and then photographed. [8] [10] However, it was not preserved.
An accurate ¾-inch scale (3½ inch gauge) working model of Earl of Airlie made by H. Thomas was awarded a Bronze Medal at the Model Engineer Exhibition of 1981. It was sold by auction by Christie's in April 2003 for a hammer price of £5,875. [2]
Under the Whyte notation for the classification of steam locomotives, 4-2-0 represents the wheel arrangement of four leading wheels on two axles, two powered driving wheels on one axle and no trailing wheels. This type of locomotive is often called a Jervis type, the name of the original designer.
A Crampton locomotive is a type of steam locomotive designed by Thomas Russell Crampton and built by various firms from 1846. The main British builders were Tulk and Ley and Robert Stephenson and Company.
Under the Whyte notation for the classification of steam locomotives, 4-2-2 represents the wheel arrangement of four leading wheels on two axles, two powered driving wheels on one axle, and two trailing wheels on one axle.
Under the Whyte notation for the classification of steam locomotives, a 2-6-4 locomotive has two leading wheels, six coupled driving wheels and four trailing wheels.
Under the Whyte notation for the classification of steam locomotives, 4-2-4 represents the wheel arrangement of four leading wheels on two axles, two powered driving wheels on one axle, and four trailing wheels on two axles.
The Great Northern Railway (GNR) No. 1 class Stirling Single is a class of steam locomotive designed for express passenger work. Designed by Patrick Stirling, they are characterised by a single pair of large driving wheels which led to the nickname "eight-footer". Originally the locomotive was designed to haul up to 26 passenger carriages at an average speed of 47 miles per hour (76 km/h). They could reach speeds of up to 85 mph.
Under the Whyte notation for the classification of steam locomotives, 0-8-4 represents the wheel arrangement of no leading wheels, eight powered and coupled driving wheels on four axles, and four trailing wheels on two axles.
The Dean Single, 3031 Class, or Achilles Class was a type of steam locomotive built by the British Great Western Railway between 1891 and 1899. They were designed by William Dean for passenger work. The first 30 members of the class were built as 2-2-2s of the 3001 Class.
The Dundee and Newtyle Railway opened in 1831 and was the first railway in the north of Scotland. It was built to carry goods between Dundee and the fertile area known as Strathmore; this involved crossing the Sidlaw Hills, and was accomplished with three rope-worked inclined planes. Newtyle was simply a remote railhead, and the anticipated traffic volumes were not achieved, the inclines incurred heavy operating costs, and the railway never made money.
Auchterhouse is a village, community, and civil parish in the Scottish council area of Angus, located 7.3 miles (11.7 km) north west of Dundee, 9.5 miles (15.3 km) south east of Alyth and 14.9 miles (24.0 km) south west of Forfar. It lies on the southern edge of the Sidlaw Hills, below Auchterhouse Hill, 1,398 feet (426 m) high. The parish, which is coterminous with the community, had a population of 520 in 2001. The village, formerly known as Milltown of Auchterhouse, straddles the B954 Muirhead to Newtyle road. About 1.0 mile (1.6 km) east lies the larger village of Kirkton of Auchterhouse, where the church and school are located.
Under the Whyte notation for the classification of steam locomotives, 0-2-4 represents the wheel arrangement of no leading wheels, two powered driving wheels on one axle, and four trailing wheels on two axles.
