FÖRSTLINGEN was the first steam locomotive built in Sweden . It was commissioned by Fredrik Sundler, who used it on the Norbergsbana and, after changing gauges, on the Nora – Ervalla järnväg .

Construction of the locomotive

At the request of Fredrik Sundler, the builder of the Norbergsbana and the Nora – Ervalla järnväg , Munktells Mekaniska Verkstad in Eskilstuna began construction in 1852. The locomotive was designed by Harald Asplund and built with a track width of 891 mm. The first test drive on the factory premises took place on June 3, 1853. After test drives, the locomotive was taken by ship to Västerås on June 6, 1853 and then on to Trättsbo to the Norbergsbana , which was under construction . There were test drives on a short stretch of road on August 8, 1853. In the autumn of 1853, around five kilometers of the line were completed and on December 1st, FÖRSTLINGEN carried the first ore train.

After Fredrik Sundler had finished his job with the Norbergsbana , he switched to his new job as a contractor for the construction of the Nora – Ervalla järnväg . At the turn of the year 1853/1854 he had FÖRSTLINGEN brought to his place of birth, Fänneslunda, northwest of Ulricehamn , via the canal and sea route , where it was converted to standard gauge . In 1854 she was transported by sea to Arboga and by land to Stora Mon near Nora. This “marvel” caused a sensation when it rolled on the road by four oxen on specially mounted wheels.

The locomotive weighed 33  skepp bungs (about 5.6 tons) and could carry a load of 16 to 17 tons. The frame consisted of two riveted iron plates with an intermediate layer of oak. Initially, the water tank was mounted under the machine. This was later changed by adding a tender to the locomotive .

FÖRSTLINGEN was used during the construction of the track and was quite worn out in the process. The locomotive was only sparsely repaired and from the opening of the line in 1855 was only rarely used for construction trains until 1869, as the traffic on the line was served by the Köping – Hults järnväg . In the meantime, the company made several unsuccessful attempts to sell the locomotive. That only succeeded in 1871, when Halldins Verkstad in Örebro bought the locomotive for 800 crowns and then scrapped it. At the time, no one recognized the cultural value that Sweden's first locomotive had.

Förstlingen II

Working copy of FÖRSTLINGEN

The original drawings have disappeared. Based on an assembly drawing of the locomotive, which was preserved in the Munktells Mekaniska Verkstad Museum in Eskilstuna, Bengt Ohlin made all the detailed drawings from scratch. Therefore, there is now a complete collection of drawings (compilation, detailed drawings and specifications). The reconstruction of all drawings was a very extensive job. Without this information it would have been impossible to build a replica of the locomotive. This replica in the original form without tender with 1435 mm gauge was put into operation in 2004.
