1859. He proposed that a wide market square should be built on the place of the Hyeena block east to the railway yard. The few buildings left in the Hyeena block were dismantled, and it was changed into what is now the Rautatientori square. Construction of the first railway station in Finland started at the edge of the Hilleri block. The construction of the railway station had a great impact on the Helsinki cityscape. The railway was piled with large logs, and stones were laid on the edge of the bay. Aspen trees had to be cut down from the Kaisaniemi Park to make way for the railway, but the park was preserved whenever it was possible to do so. Rock blasted off the Linnunlaulu cliff was sunk into the Töölönlahti bay beneath the railway tracks being constructed. The railway terracing over the Töölönlahti bay was completed in March 1861. For water traffic, two underpass bridges were built vaulted from stone. The larger underpass bridge had a size of 7 cubits and the smaller one had a size of 3 cubits. The rails for the railway tracks were bought from the United Kingdom, and they arrived by steamship into the South Harbour in November 1857. Helsinki's first station Helsinki's first railway station was built in 1862 to accommodate trains on the Helsinki–Hämeenlinna line, päärata. The station's plans were drawn by Swedish architect Carl Albert Edelfelt. According to the original plans, all station buildings along the Helsinki-Hämeenlinna line should have been built from wood. However, there soon came wishes that the station building in the capital should be built from a more valuable material. Railway construction was new to Finland, and thus there were no existing models for new station buildings. So the provincial architect of Tavastia, Carl Albert Edelfelt, was requested for plans for various alternatives, which were presented in October 1859. The cost estimate for a smaller one-floor building was about 27 thousand roubles and that for a larger two-floor building was about 40 thousand roubles. A wooden station building would only have cost 18 thousand roubles. These estimates did not include the cost for pile-driving the foundation, which was high at the muddy shore of the Kluuvinlahti bay. Commercial counsellor Henrik Borgström and chief director von Born supported the construction of the smallest possible wooden building as a temporary station building, as passenger numbers would be fairly small
