The Soviet locomotive class IS (Russian: ИС) was a Soviet passenger steam locomotive type named after Joseph Stalin (Russian: Иосиф Сталин). The contract design was prepared in 1929 at the V.V. Kuybyshev Locomotive Factory in Kolomna. The IS series locomotives were manufactured between 1932 and 1942.

Overview

The locomotive used the same cylinders and boilers as the FD series locomotives. However the IS steam locomotive had a 2-8-4 wheel arrangement.

Construction

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 October Revolution Locomotive Factory in Voroshilovgrad. In total, 649 IS steam locomotives were constructed. Later the series was renamed FDP (steam locomotive FD, passenger modification).

Use

These locomotives were used until 1972.
