The Danish series JFJ F were C -tender locomotives with a two-axle tender for the freight train operation of Jysk-Fyenske Jernbaner (JFJ). The four examples of this wet steam design were supplied by Hawthorn, Leslie & Company , Newcastle upon Tyne in 1873 and designated as F 61–64.
history
In 1874, the JFJ opened the railway line from Lunderskov via Esbjerg to Varde , followed a year later by the section of Vestjyske Længdebane from Varde via Ringkøbing and on to Holstebro . For this purpose, the company procured 16 new locomotives in three different series. All of these locomotives were built by Hawthorn, Leslie & Company, Newcastle-upon-Tyne, England . The manufacturer was already known for its Crampton locomotives for the Sjællandske Jernbaneselskab (SJS), which were delivered as the Roeskilde class in 1854 .
The four freight locomotives No. 61-64 were run as separate series after delivery in February and March 1874, as was common in the early days of the series designation among other things at the JFJ, and were only combined as series F at an unknown time .
Technical design
The fire box was between the two rear wheelsets . The cylinders were slightly above the center of the axle. The locomotives had internal slide rails and an internal Stephenson control . The front wall of the smoke chamber was vertical.
The steam boiler was equipped with two safety valves , a Salter valve in the steam dome and a Naylor valve on the combustion chamber. The cab had an almost flat wooden roof. The sandboxes were located under the maneuvering steps directly in front of the front wheelset. The oval company signs in the form of cast iron plates were attached to the sandboxes. There was only a screw handbrake on the small tender.
Conversion to a tank locomotive
These four locomotives were used for a short time from Esbjerg and then transferred to Aarhus , from where they drove special freight trains. In 1885 they came to Funen . There were Saugluftbremsen built for locomotive and tender.
Since stronger shunting locomotives were now needed, the F 61 , F 62 and F 64 and in 1890 the F 63 were converted into C-coupled tank locomotives in the workshop in Århus . Parts of the tenders were used for the water boxes. In addition, some smoke pipes were removed and the locomotives were fitted with a vapor barrier , but not with a handbrake . If the machines were turned off, they had to be secured with drag shoes .
After the renovation, two locomotives came to Århus, the other two to Vamdrup . They always stayed in Jutland .
DSB F / DSB F (I)
When Jysk-Fyenske Jernbaner and Det Danske Jernbanedriftselskab merged on September 1, 1867, the locomotives came to the newly founded Danske Statsbaner . The pooling of equipment departments in the country took place only in 1892. In the newly established numbering plan, the locomotives were given the series designation DSB F . When further C-coupled tank locomotives were procured for shunting service from 1898, they were added to the F (I) series .
Further remodeling and whereabouts
From this point on, the four machines were assigned easier tasks again. They were used in the railway depot ( Danish maskindepot ) Århus, in Horsens, Langå , Randers, Frederikshavn and Struer . In 1899 all four locomotives received new boilers.
Whereabouts
F 61 was the last locomotive to be retired on October 11, 1939 and then scrapped in Copenhagen. It had been out of service since 1935, after having worked for the Horsens port railway for the last year .
F 62 was parked in Århus in 1935 and retired on March 28, 1935, F 63 was in service in Horsens until 1934 and was retired on January 8, 1935, both of which were scrapped at HI Hansen in Odense in the same year. F 64 was deposited in Frederikshavn in 1936 and retired on June 22, 1936. A planned sale of the locomotive to Randers-Hadsund Jernbane (RHJ) failed, so that it was also scrapped at Hansen.
