Swiss North 4-4-0 Locomotives in Switzerland
Class Details by Steve Llanso of Sweat House Media
Class 116 (Locobase 6789)
Data from the table presented on pages 370, 372 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 Jury report says that this locomotive was designed to pull a 240-ton train up a 1% grade at 45-50 km/h (28-31 mph). The exhibition example was works #1266.
Class Rhein (Locobase 792)
Designed by Emil Kessler and based on the Norris Brothers design, the Rhein and Reuss had a short-wheelbase leading truck, horizontal cylinders ahead of the trucks, the firebox between the driving axles, and a modified "haystack" boiler dome over the firebox. They succeeded the 4-2-0 Norris-type engines that were the first locomotives in Switzerland; see Limmat entry.
