Roskilde 4-2-0 Locomotives in Denmark
Class Details by Steve Llanso of Sweat House Media
Class Roeskilde (Locobase 3963)
Data from William Bay, Danmarks Damplokomotiver (1977). Class information from [
].
Photos on the Danish Damplokomotiver hos DSB ([]) website show a Crampton-type engine with relatively tall drivers. According to Jernbane.dk, the engines were actually built by Thomas Crampton at Tulk & Ley in 1849.
By the time they came to the Roskilde, they were so clapped out that they were retired in 1864-1867.
