Roskilde-Kors'r / SJS / DSB 2-4-0 Locomotives in Denmark
Class Details by Steve Llanso of Sweat House Media
Class Loke / Gs (Locobase 3965)
Data from William Bay, Danmarks Damplokomotiver (1977). Class data from [
].
According to Jernbanen.dk, this quintet was procured in response to a jump in freight traffic after the RH was opened. When they entered service, the engines were named St'rkodder, Skold, Loke, Heimdal, & Aegir. The highest numbered 3 engines had been produced in 1858; 216 came in 1864 and 215 in 1866.
When the successor Zeeland Railway merged with the Jutland-Funen Railway in 1892, the former brought this class of small 4-coupled passenger engines into the motive power roster. Three of the five Lokis -- Gs 216, 218, 219 -- were almost immediately withdrawn and scrapped. 215 and 217 were converted to stationary boilers at the Vamdrup Electricity Works.
