Economy

After regaining her independence Poland was faced with major economic difficulties. In addition to the devastation wrought by World War I, the exploitation of the Polish economy by the German and Russian occupying powers, and the sabotage performed by retreating armies, the new republic was faced with the task of economically unifying disparate economic regions, which had previously been part of different countries. Within the borders of the Republic were the remnants of three different economic systems, with five different currencies (the German mark

) and with little or no direct infrastructural links. The situation was so bad that neighboring industrial centers as well as major cities lacked direct railroad links, because they had been parts of different nations. For example, in the 1920s there was no direct railroad connection between Warsaw and Kraków, and the line was not completed until 1934.

On top of this was the massive destruction left after both World War I and the Polish Soviet War. There was also a great economic disparity between the eastern (commonly called Poland B) and western (called Poland A) parts of the country, with the western half, especially areas that had belonged to the German Empire

Transport

According to the 1939 Statistical Yearbook of Poland, total length of railways of Poland (as for December 31, 1937) was 20 118 kilometers. Rail density was 5.2 km. per 100 km2. Railways were very dense in western part of the country, and in the east, especially Polesie, rail was non-existent in some counties. During the interbellum period, Polish government constructed several new lines, mainly in central part of the country (see also Polish State Railroads Summer 1939). Construction of Warszawa Główna railway station was never finished due to the war, and Polish railroads were famous for their punctuality (see Luxtorpeda

In the interbellum, road network of Poland was dense, but the quality of the roads was very poor - only 7% of all roads was paved and ready for automobile use, and none of the major cities were connected with each other by a good-quality highway. In the mid-1930s, Poland had 340,000 kilometers of roads, but only 58,000 had hard surface (gravel, cobblestone

), and 2,500 were modern, with asphalt or concrete surface. In different parts of the country, there were sections of paved roads, which suddenly ended, and were followed by dirt roads. Poor condition of roads was the result of both long-lasting foreign dominance, and inadequate funding. On January 29, 1931, Polish Parliament created State Road Fund, whose purpose was to collect money for construction and conservation of roads. The government drafted a 10-year plan, with road priorities: a highway from Wilno, through Warsaw and Cracow, to Zakopane (called Marshall Pilsudski Highway), asphalt highways from Warsaw to Poznań and Łódź, as well as Warsaw ring road. However, the plan turned out to be too ambitious, as there was not enough money in the national budget. In January 1938, Polish Road Congress estimated that Poland should spend on roads three times more money to keep up with Western Europe.
