William Dean, Armstrong's successor, designed (among others) four classes of locomotive, 2-4-0 and 0-6-0 tender and tank engines, which shared many standard components. However, it was Churchward who carried the policy to lengths which made GWR locomotives distinctive and shaped their development until the nationalisation of the railways .
In statistics, Duncan's new multiple range test (MRT) is a multiple comparison procedure developed by David B. Duncan in 1955. Duncan's MRT belongs to the general class of multiple comparison procedures that use the studentized range statistic q r to compare sets of means.
In mathematics, the comparison test, sometimes called the direct comparison test to distinguish it from similar related tests (especially the limit comparison test), provides a way of deducing whether an infinite series or an improper integral converges or diverges by comparing the series or integral to one whose convergence properties are known.
The heaviest class of 4-6-0 's ever put into series production was the Pennsylvania Railroad class G5 with 90 examples completed in the mid-1920s, which were some 5,500 pounds (2.5 t) lighter. One of the B&O's 4-6-0 s, built in 1869, is preserved at the B&O Railroad Museum in Baltimore. Another is at the National Museum of Transportation in St ...
They were also regarded as a powerful upgrade from both of the older Compound 4-4-0 locomotives, both the MR 1000 Class and the LMS Compound 4-4-0 as well. The Jubilees were a rather common sight on the Midland Main Line , the West Coast Main Line , and the Settle-Carlisle line , but were eventually displaced by the much more powerful Royal ...

Then the Patriots (Baby Scots) were introduced, which were bigger than a class 5 Dreadnought but smaller than a Royal Scot. The Jubilees are basically Unrebuilt Patriots with taper boilers. BR reorganised the system so that 5XP was eliminated, and 5XP-->6P, 6P-->7P and 7P-->8P.
The Pennsylvania Railroad G5 is a class of 4-6-0 steam locomotives built by the PRR's Juniata Shops in the mid-late 1920s. It was designed for passenger trains, particularly on commuter lines, and became a fixture on suburban railroads (notably the Long Island Rail Road ) until the mid-1950s.
