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 October Revolution Locomotive Factory in Voroshilovgrad, Ukrainian SSR (Luhansk, Ukraine). In total, 649 IS steam locomotives were constructed. Later the series was renamed FD^P (steam locomotive FD, passenger modification).

Use

These locomotives were used until 1972.
