Varde-Grindsted Jernbane 2-6-2 Locomotives in Denmark
Class Details by Steve Llanso of Sweat House Media
Class 5 (Locobase 11250)
Data from William Bay, Danmarks Damplokomotiver (1977). [
] . Works number was 67 in 1925.
This 44.3-km (27.5-mile) line opened in 12 April 1919 with hand-me-down locomotives, so this was the first new-built locomotive operated by the railway. It was one of the smallest standard-gauge Prairie tanks to have been built for any service.
