context: The history of the Finnish rail network can be considered as extending to at least March 20, 1849, when Colonel Alfred Stjernvall, the head of the civil engineering department, proposed the construction of a horse-drawn railway from Helsinki to Turkhau. The track would have crossed the Salpausselkä and connected the country's capital to the navigable Lake Finland. The Governor-General ordered the matter to be investigated, and in 1851 a plan for the construction of a locomotive railway from Helsinki to Hämeenlinna was completed. [1] The first section of the Finnish railway network, which is now part of Finland's main line, was opened in 1862 for this section. [2] At the end of the 19th century, trains in Finland were designed to run at only 25 kilometers per hour, making travel slow but still faster than riding on horseback.
