SM48 is the name for class of Soviet diesel locomotives operating in Poland for PKP. The original designation was ТЭМ2 (TEM2), and was the Soviet-built version of the ALCO RSD-1.

History

The SM48 was originally put into service on the eastern Polish railways, where 1,524 mm (5 ft) Russian broad gauge railways were still in use. In fact, the locomotive coped well with the structure gauge on standard gauge lines.

Introduction

Since 1976, PKP have bought 130 SM48 locomotives. There are also locos in service with other Polish operators: PCC Rail, PTKiGK Zabrze, Kopalnia Piasku Kotlarnia.

Starting from 2010, several locomotives undergo a modernization to ST48 standard.
