Production
The most visible difference between No.97 and the first of the 1905 production batch was the higher pitch of the boiler (8 ft 2 in/2.49 m opposed to 7 ft 8 1⁄2 in/2.35 m). At first the prototype was given a 4,000-imperial-gallon (18,000 l; 4,800 US gal) tender but almost without exception the 2800s were harnessed to the 3,500-imperial-gallon (16,000 l; 4,200 US gal) variety throughout their working lives. Superheating was incorporated into the class from 1909 with No.2808 the first to be retro-fitted. Other modifications centred on improving the weight distribution, altering smokebox lengths and fitting larger diameter chimneys. The 84 2800s built by Churchward remained the GWR's principal long haul freight engines throughout the 1920s and 1930s. The only serious problem met with in traffic was with the sealing of the internal steam pipes. Beginning in 1934 most of the class had them replaced with the outside kind.

Famous quotes containing the word production:
“The development of civilization and industry in general has always shown itself so active in the destruction of forests that everything that has been done for their conservation and production is completely insignificant in comparison.”
—Karl Marx (1818–1883)
“By bourgeoisie is meant the class of modern capitalists, owners of the means of social production and employers of wage labor. By proletariat, the class of modern wage laborers who, having no means of production of their own, are reduced to selling their labor power in order to live.”
—Friedrich Engels (1820–1895)
“Constant revolutionizing of production ... distinguish the bourgeois epoch from all earlier ones. All fixed, fast-frozen relations, with their train of ancient and venerable prejudices are swept away, all new-formed ones become antiquated before they can ossify. All that is solid melts into air, all that is holy is profaned, and man is at last compelled to face with sober senses, his real conditions of life, and his relations with his kind.”
—Karl Marx (1818–1883)
