Prussian State 2-4-2 Locomotives in Germany
Class Details by Steve Llanso of Sweat House Media
Class P 3 (Locobase 6345)
Data from Christian Lindecke data from [
] (14 Nov 2004).
Lindecke shows 44 metric tons for the adhesion weight, which seems much too high. 24 metric tons results in a more reasonable factor of adhesion and a more likely percentage of total weight on the drivers.
Class T5.1 / BR 71 (Locobase 2136)
Data from the table presented on pages 405, 407 of the Groupe VI. - GTnie civil. - Moyens de transport. DeuxiFme partie. Classes 32 (Tome I), part of the series of Rapports du Jury Internationale of the Exposition Unverselle Internationale de 1900 Paris Exposition, hosted on the website of Le Conservatoire numTrique des Arts & MTtiers ([], Accessed 21 August 2005).
The T5 was rated at 65 km/h (40 mph) when it ran on the Hesse States' Main-Neckar bahn.
