Pensnet Railway 0-4-0 Locomotives in Great_Britain

Class Agenoria (Locobase 5595)

Like her sister, the Stourbridge Lion, this engine harked back to the colliery locomotives of William . See [] for details on Agenoria's first day in service. She pulled an 12-carriage train, 8 of the carriages holding 364 passengers, the other four filled with 3 1/2 tons of coal. A second run displayed her coal-hauling capabilities, while a third conveyed a few special passengers at a sparkling 11 mph.

The vertical cylinders were operated by a gangling walking-beam type valve motion. As Hollingsworth (1982) notes, the arrangement actually consists of two engines in one. The single flue doubled on itself but eventually exhausted up the very tall stack. However outdated the design almost immediately became, it was clearly satisfactory enough. Agenoria continued in service until 1865.

The 1907 Catalogue of Mechanical Engineering Collection in the Science Division of the Victoria & Albert Museum (Board of Education South Kensington)., pp 92. (page 75) gave a full description of the boiler and grate:

"The grate is contained in a furnace tube 29 in. diam., which branches into two flues, each 18 in. diam., through which the heated gases pass to a chamber at the forward end ; this

chamber is completely within the shell and it communicates with the chimney by a short vertical tube passing through the upper part of the barrel. The back-end plate carries the furnace and flues and is attached to the barrel by bolts, thus enabling the whole of the internal portion of the boiler to be easily removed for cleaning or repairs. The boiler is

fitted with a dome surmounted by a spring-loaded safety-valve and was originally provided, in addition, with a " lock-up " safety valve ; a single feed-pump is provided which is driven from one of the grasshopper beams. The exhaust steam is turned into the chimney, but, from the exceptional height of the latter, it is probable that this blast was not

utilised to increase the draught; at the time the engine was built, great objections were raised to the noise of locomotives, and also to the smoke given off ; these annoyances would be reduced by a quiet exhaust and a tall chimney."
