Soviet locomotive class IS ( Russian: ИС) was a Soviet passenger steam locomotive type. The contract design was prepared in 1929 at the Kolomna factory. The ИС were manufactured between 1932 and 1942. They were named after Joseph Stalin ( Russian: Иосиф Сталин).
Overview [ edit ]
The steam locomotive was a 2-8-4. The locomotive used the same cylinders and boilers as the
ФД (FD) series locomotives. However the ИС steam locomotive had a different wheel arrangement.
Construction [ edit ]
The first steam locomotive was released from the Kolomna factory on October 4, 1932. In April–December a steam locomotive was tested on the October-, Southern- and Ekaterinenskaya railways.
In 1936 production began at the
Voroshilovograd factory. In total, 649 steam locomotives were constructed. Later it was renamed FDP ( steam locomotive FD, passenger modification).
These locomotives were used until 1972.
