The Queensland Railways C19 class locomotive was a class of 4-8-0 steam locomotives operated by the Queensland Railways.

4-8-0 locomotive wheel arrangement

Under the Whyte notation for the classification of steam locomotives, 4-8-0 represents the wheel arrangement of four leading wheels on two axles, usually in a leading truck or bogie, eight powered and coupled driving wheels on four axles and no trailing wheels. In North America and in some other countries the type was usually known as the Mastodon and sometimes as the Twelve-wheeler.

Steam locomotive Railway locomotive that produces its pulling power through a steam engine

A steam locomotive is a type of railway locomotive that produces its pulling power through a steam engine. These locomotives are fueled by burning combustible material – usually coal, wood, or oil – to produce steam in a boiler. The steam moves reciprocating pistons which are mechanically connected to the locomotive's main wheels (drivers). Both fuel and water supplies are carried with the locomotive, either on the locomotive itself or in wagons (tenders) pulled behind.

History

The C19 class was designed as a superheated version of the C18 class. Per Queensland Railway's classification system they were designated the C19 class, C representing they had four driving axles, and the 19 the cylinder diameter in inches.

A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming. There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet.

The Queensland Railways C18 class locomotive was a class of 4-8-0 steam locomotives operated by the Queensland Railways.

Driving wheel powered wheel of a railway locomotive

On a steam locomotive, a driving wheel is a powered wheel which is driven by the locomotive's pistons. On a conventional, non-articulated locomotive, the driving wheels are all coupled together with side rods ; normally one pair is directly driven by the main rod which is connected to the end of the piston rod; power is transmitted to the others through the side rods.

The North Ipswich Railway Workshops built 20 between 1922 and 1928. A further six were built by Walkers Limited in 1935. They worked the heavily graded Main, Southern, North Coast and Western lines. [1] [2] [3]

North Ipswich Railway Workshops railway workshops in Queensland, Australia

North Ipswich Railway Workshops is a heritage-listed former Australian railway workshop at North Street, North Ipswich, Queensland. It was built from 1878 to 1980s. It is also known as the Workshops Rail Museum. It was added to the Queensland Heritage Register on 21 April 1997.

Walkers Limited Australian locomotive manufacturer

Walkers Limited was an Australian engineering company, based in Maryborough, Queensland. It built ships and railway locomotives. The Walkers factory still produces railway locomotives and rolling stock as part of Downer Rail.

Main Line railway, Queensland railway line in Queensland, Australia

The Main Line is a railway line in South East Queensland, Australia. It was opened in a series of sections between 1865 and 1867. It commences at Roma St Station in Brisbane and extends west 161 km to Toowoomba. It is the first narrow gauge main line constructed in the world. The section of the line from the end of Murphys Creek railway station to the Ruthven Street overbridge, Harlaxton is listed on the Queensland Heritage Register. The Murphys Creek Railway Complex, the Lockyer Creek Railway Bridge (Lockyer), the Lockyer Creek Railway Bridge and Swansons Rail Bridge are also heritage listed.

Nº 702 entered traffic in December 1923 and was named Centenary as it was the hundredth engine constructed by North Ipswich Railway Workshops. In April 1927, 699 operated a Royal train carrying the Duchess of York and in December 1934, 700 carried the Duke of Gloucester. [2]

A royal train is a set of railway carriages dedicated for the use of the monarch or other members of a royal family. Most monarchies with a railway system employ a set of royal carriages.

Queen Elizabeth The Queen Mother Queen consort of King George VI, mother of Queen Elizabeth II

Elizabeth Angela Marguerite Bowes-Lyon was the wife of King George VI and the mother of Queen Elizabeth II and Princess Margaret, Countess of Snowdon. She was Queen consort of the United Kingdom and the Dominions from her husband's accession in 1936 until his death in 1952, after which she was known as Queen Elizabeth The Queen Mother, to avoid confusion with her daughter. She was the last Empress consort of India.

Prince Henry, Duke of Gloucester

Prince Henry, Duke of Gloucester, was the third son and fourth child of King George V and Queen Mary. He served as Governor-General of Australia from 1945 to 1947, the only member of the British royal family to hold the post.

A number of modifications were made over the years. The early engines had a large regulator dome and another smaller one for the safety valves similar to the B17 class. Those built from 1926 onwards had a boiler with only one small dome that contained both regulator and safety valves. Earlier engines later received this type as they became due for re-boilering. Both the initial and the subsequent boilers shared a firebox having a long, narrow grate which required considerable effort on the part of the fireman, and rendered them unpopular. [1]

The Queensland Railways B17 class locomotive was a class of 4-6-0 steam locomotives operated by the Queensland Railways.

The engines suffered from a number of defects and were prone to cracked frames. As their condition deteriorated and with the introduction of modern engines and later DEL for heavy traffic, the engines were relegated to lesser duties and most were withdrawn during the 1950s. Three engines that had been written off the books were returned to service for short periods in the late 1950s to overcome motive power shortages at that time.

Nº 800 was retained at Maryborough as a stationary steam plant for some years after being written off in April 1956.

Maryborough railway station, Queensland

Maryborough railway station is a heritage-listed railway station at Lennox Street, Maryborough, Fraser Coast Region, Queensland, Australia. It is on the North Coast line serving the city of Maryborough. It was designed by Chief Engineer of the Queensland Railways Department and built from 1878 to 1890 by John Roddam & John Walker. It was added to the Queensland Heritage Register on 21 October 1992.

Several C19 tenders were kept in a pool at Ipswich after their engines had been withdrawn. These tenders were then fitted temporarily to overhauled C17/B18¼/BB18¼ engines that were ready to return to service but their respective tenders were not yet available.

The last engine in service was Nº 700 at Toowoomba and was written off the books in February 1964.

The British Railways Standard Class 5MT 4-6-0 was one of the 12 standard classes of steam locomotive built by British Railways in the 1950s. It was essentially a development of the LMS Stanier Class 5 4-6-0. A total of 172 were built between 1951 and 1957.

The New Zealand A class were a class of steam locomotives built in 1906 with a 4-6-2 wheel arrangement for the New Zealand Railways Department (NZR). The class should not be confused with the older and more obscure A class of 1873. They were designed by the NZR's Chief Mechanical Engineer, A. L. Beattie and his Chief Draughtsman, G. A. Pearson to replace less powerful locomotives struggling with increasing loads on the South Island Main Trunk Railway, and in anticipation of the traffic volumes that would be created upon the completion of the North Island Main Trunk Railway.
