The LG P5 series was a narrow-gauge steam locomotive with a tender for the Lithuanian State Railways Lietuvos Gelezinkeliai (LG) with an E wheel arrangement and a gauge of 750 millimeters. The locomotives were developed and built by Škoda in Plzeň in 1934 . They were among the most powerful steam locomotives in this gauge.
history
The P5 series is one of the few new locomotives acquired by LG in the period between the beginning of Lithuanian independence in 1918 and the Soviet occupation of Lithuania in 1940.
In addition to its route network in European standard gauge of 1,435 millimeters, the LG also operated an extensive narrow-gauge network with 750 mm gauge in northeast Lithuania, which was 125 kilometers long in 1929. In the 1930s, plans were developed for an extensive network in this gauge with a total of 860 kilometers network length, partly as a new construction, partly as a conversion from existing narrow-gauge railways with 600 mm gauge. The first line to be re-tracked was the route from Biržai to Šiauliai in 1935 . The track from Žeimeliai to Joniškis was changed . In 1938 a new line was built from Joniškėlis to Panevėžys , where there was a connection to the 750 mm line to Švenčionėliai , which was built between 1892 and 1894 . In 1939, the last full year of independence, the LG owned a total of 284 km of lines with 750 mm gauge. The LG procured new locomotives for these routes as the previous vehicles were no longer sufficient. A total of 10 new steam locomotives were purchased in addition to various railcars . The supplier was the Czech company Škoda , which was the LG's “house supplier” during the time of Lithuania's first independence and, with a few exceptions, supplied all of the steam locomotives acquired during this period. The P5 series was delivered in 1934, the Mikado locomotives of the P4 series came in 1939 to LG.
The five P5 locomotives with the road numbers 51 to 55 and the Škoda factory numbers 794-798 were approved for a top speed of 40 km / h and were very powerful for narrow-gauge locomotives. During test drives, they managed trains with up to 450 tons on an incline of 1 to 200 at 36 km / h. They were mainly used on the newly built or re-tracked routes around Panevėžys. Characteristic of the wood-fired superheated steam locomotives were the outer frame and counterweights lying outside the frame . A special feature of the P5 series was its financing. Since the LG suffered in the time of the first independence of Lithuania under considerable financial problems, the five locomotives were in kind paid - Lithuania delivered as payment geese , then one of the main exports of the country. How many geese made up the equivalent of a locomotive is not documented.
It is unclear to what extent the Škoda locomotives were still used on the Lithuanian routes after the Second World War . None of the locomotives survived.
