Netherlands State 4-4-0 Locomotives in Netherlands
Class Details by Steve Llanso of Sweat House Media
Class 27 (Locobase 6787)
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 ([

Most noticeable difference between this design and most other Eight-wheelers of the time is the set of large-diameter Serve fire tubes with eight internal ribs. Otherwise, this is a relatively small locomotive with a Belpaire firebox.
