All of these received new boilers in 1905-1906. In later years, the class acted as shunter as well as motive power for lightly traveled secondary lines.
The least of these engines -- As 2 -- served the SJS and successor DSB for over four decades before being withdrawn in 1921 following an accident in the switchyard. As 3 was withdrawn in the same year. The two remaining As were withdrawn 8 years later in 1929.

When the SJS planned for the opening of the Frederikssund line in Summer 1879, they went to Esslingen for 5 small passenger engines they named Tjalfe, Roskva, Vaulundur, Rimfaxe, and Yrsa.
Ten years later, because the class met the requirements quite satisfactorily and because they were opening the Slagelse-Dalmose-N'stved line, the SJS returned to Esslingen for 2 more.
The last 3 were the first to be withdrawn in 1899-1901, which suggests the purchase of the last two was quickly seen as a mistake. Bs 292 went next in 1908, while Bs 289 and Bs 291 were retired in 1917.
Bs 290 was sold in 1918 to the Varde - N'rre Nebel Jernbane (VNJ) and served that railway as its #7 until it was sold for scrap in 1927.

This quartet was produced to meet the increased traffic demand on the Slagelse-Dalmose-N'stved line, which opened in 1891.
All four were sold in 1918 to open the Varde - Grindsted Jernbane (VaGJ) privatebane as their 1-4. The VaGJ opened officially on 12 April 1919; it covered 44.3 km (27.5 miles) in central Denmark. Three were scrapped in 1930; #2 was withdrawn in 1930, but not scrapped until 1952.
Data from WilliamBay, Danmarks Damplokomotiver (1977). Class information from []. Esslingen produced 7 engines in 1875, 2 in 1876, and 3 in 1877.
Four of the class served Danish railways for as little as 30 years -- CS 238 was retired in 1898, CS 247 in 1900, CS 248 in 1901, and CS 245 in 1906. The rest ran for more than 5 decades each. CS 240 and CS 242 were scrapped in 1925, CS 239 and CS 243 in 1928, CS 241 and CS 245 in 1929, CS 249 in 1931, and finally CS 246.
CS 246 went into the Railway Museum and was displayed in several cities over the next several decades.
