A reproduction 4-4-0 steam locomotive hauls passengers over 10 miles of Northern Central Railway track between New Freedom and Hanover Junction, Pennsylvania. [1] The operation was originally named Steam into History and held its grand opening on June 1, 2013. [2] In 2019 it took up the historical name Northern Central Railway. [3]
One is a new sort of steam pump, essentially two devices like de Caus', but attached to a single boiler. A key invention is the addition of cooling around the containers to force the steam to condense. This produces a partial vacuum inside the chambers, which is used to draw a volume of water into the containers through a pipe, thus forming a pump.

Steam just above atmospheric pressure (all that the boiler could stand) was introduced into the lower half of the cylinder beneath the piston during the gravity-induced upstroke; the steam was then condensed by a jet of cold water injected into the steam space to produce a partial vacuum; the pressure differential between the atmosphere and the ...
Steam ejected tangentially from nozzles caused a pivoted ball to rotate. This suggests that the conversion of steam pressure into mechanical movement was known in Roman Egypt in the 1st century, however, its thermal efficiency was low. Heron also devised a machine that used air heated in an altar fire to displace a quantity of water from a ...
Steam into History 4-4-0 No. 17 "York". Completed in 2013 by the Kloke Locomotive Works. Although not based on a specific locomotive aside from the looks of American steam locomotives in the 19th century, it is still considered a newbuilt. It runs on oil instead of wood. Central Pacific Leviathan, a 4-4-0. Completed in 2009 by the Kloke ...
The last steam-hauled service trains on the British Railways network ran on 11 August 1968, but the use of steam locomotives in British industry continued into the 1980s. [22] In June 1975, there were still 41 locations where steam was in regular use, and many more where engines were maintained in reserve in case of diesel failures. [ 23 ]
