Fireless engines "Krupp" (left) and "Hohenzollern" (right) seen at the
<a href="http://www.rimkoeln.de/">RIM</a> (Rheinisches Industriebahn-Museum
K&ouml;ln-Nippes) on 12 October 2003. Note that the "Hohenzollern" has the
cylinders inside the frame, the intention of this construction was a better
thermal insulation leading to lower steam consumption.
