Class Details by Steve Llanso of Sweat House Media

Class F (II) (Locobase 4015)

Data from William Bay, Danmarks Damplokomotiver (1977). Works numbers from [] . According to Jens Vesterdahl's Danish Steam Locomotives site -- [] (9 July 2003) -- locomotives were added to this class from 1898-1923, plus another 15 in 1949. Over that time, engines were supplied by Frichs (Denmark); Hanomag, Borsig, Henschel, Hnttemeier -- all German builders; Tubize (Belgium); Breda and Saronno (Italy).

The order of road numbers is not the same as the order of production. The latter is listed below:

Year Builder Road numbers

1898 Saronno 491-499 (and 500 in 1899)

1900 Breda 486-490

1901 Hnttemeier 477-480

1901 Hanomag 481-485

1903 Henschel & Sohn 471-474

1909 Borsig 457-470

1910 Hanomag 453-456

1912 Tubize 447-452

1913 Frichs 444-446 (works 1-3)

1914 Frichs 441-443 (6, 5, 4)

1919 Frichs 423-427 (7-11)

1920 Hanomag 436-440

1920 Frichs 686-695 (12-21)

1921 Frichs 696-700 (22-26)

1922 Frichs 676-685 (27-36)

1923 Frichs 666-675 (42-51)

1949 Frichs 651-665 (355-362, 367-373)

Photos show how prominently the steam dome sat on the boiler - it seems outsized compared to those of most other locomotives.


Class F (III) (Locobase 4027)

Data from William Bay, Danmarks Damplokomotiver (1977). Class information from [].

This last class of 6-coupled tank shunters (switchers or Rangerlokomotiven) came from Switzerland, probably because the German companies that usually supplied the DSB were otherwise occupied with World War One. These trim little engines also headed up passenger locals on several lines.

All served into the 1960s, the earliest retirement coming in 1963 (5 of the class) and the last in 1967. 428 was preserved.


Class G (III) (Locobase 4012)

Data from WilliamBay, Danmarks Damplokomotiver (1977). See also [].

Twenty of this class was superheated beginning in 1913; see Locobase 11244.


Class G (III) - superheated (Locobase 11244)

Data from WilliamBay, Danmarks Damplokomotiver (1977) and from Malskema , a table of locomotives reproduced on .

Beginning not long after the last deliveries of the saturated-boiler G (III)s (Locobase 4012) , the DSB superheated 20 of the large class of 6-coupled freighters. 3 were modified in 1913, 4 in 1914, 2 in 1915, 1 in 1916, 3 in 1917. After a break of 6 years, 4 more were superheated in 1923 and 1 more in 1924. Five more of the slightly earlier G (II)s (Locobase 4006)were also superheated in the late 1920s -- 1 in 1926, 2 in 1927, 1 in 1929, and the last in 1932.

The result was a bigger boiler pressed to a greater degree.
