By 1840 the 2-2-0 tender type had largely been superseded by the 2-2-2 configuration. However, there are a few examples of later tank engines , thus William Bridges Adams of the Fairfield Locomotive Works ( 51°31′52″N 0°01′19″W / 51.5312°N 0.0219°W / 51.5312; -0.0219 ) in Bow supplied a 2-2-0 well tank to the Roman ...
Under the Whyte notation for the classification of steam locomotives, 2-2-2-0 usually represents the wheel arrangement of two leading wheels on one axle, four powered but uncoupled driving wheels on two axles, and no trailing wheels, but can also be used to represent two sets of leading wheels (not in a bogie truck) two driving wheels, and no trailing wheels.
The Pennsylvania Railroad no. 1320 was a single experimental passenger three-cylinder compound 2-2-2-0 locomotive purchased by the Pennsylvania Railroad in 1889, based on the London and North Western Railway's (LNWR) Dreadnought class, designed by Francis Webb.
The design was not successful and the locomotives were withdrawn by 1867. It would later be used on the Royal Bavarian State Railways ML 2/2 class of 1906, which were much more numerous and successful. The Mount Washington Cog Railway has eight 0-2-2-0's and only two are in working order, with three in storage and the remainder on display.
The London and Greenwich Railway began a public service on the 2 + 1 ⁄ 2 miles (4.0 km) section between Spa Road and Deptford in February 1836. [25] Locomotives in use at this point were two Planet type of the 2-2-0 configuration. Royal William was supplied by William Marshall & Sons.
Campbell patented his 4-4-0 design in February 1836, [1] [2] just a few months before the patent law was changed to require that claims include proof of originality or novelty. [3] The 4-4-0 or American type steam locomotive was the most popular wheel arrangement in 19th century American railroads and was widely copied. [2]
A later Locomotive BASIC was BASIC2 for Digital Research's GEM graphical user interface, as supplied with the Amstrad PC1512 and PC1640 range of PC clones. The company also developed the LocoScript word processor for the PCW, which was a complete bootable environment in its own right with no separate underlying operating system . [ 3 ]
The Patentee locomotive was a revolutionary 2-2-2 steam locomotive type introduced by Robert Stephenson and Company in 1833, as an enlargement of their 2-2-0 Planet type. The wheel arrangement of two leading wheels on one axle, two powered driving wheels on one axle, and two trailing wheels on one axle provided more stability and enabled a larger firebox than the earlier 0-2-2 and 2-2-0 types.
