There is no doubt that the railway influenced importantly the whole region of the Sázava Basin, mainly as concerns its economy. It is even very hard to imagine what would the life in here look like if the railway was not here. There are still many places along the Sázava River that are inaccessible otherwise than by train. Building of the Posázavský Pacifik railway was initiated towards the end of the 19th century. Except for its short segment from Prague-Vršovice to Prague-Modřany, was the whole of the railway from Modřany, through Davle, along the Sázava River up to Světlá nad Sázavou built at the turn of the 19th and 20th century.
