SM03 is the name of a Polish diesel locomotive class in the PKP railway operator designation. The letters "SM" describe a diesel shunting locomotive.

Technical data

It is a small (110 kW) shunting locomotive with mechanical transmission. Power from the engine is transmitted to wheel sets through the main clutch and quadruple gearbox.

Engine

The SM03 is powered by a fourstroke, six-cylinder diesel engine with automatic ignition and rated power of 150 hp.The engine is started by an electric starter, powered from a 300 Ah acid batteries.

Gearbox

Locomotives of this series were built with two types of gearbox: first had one speed range (factory number: Ls150), and the other a quadruple gearbox with two speed ranges (factory number: 2Ls150). Accordingly, the former had a maximal speed of 25.7 km/h, and the letter was capable of 45.8 km/h.Gearbox steering is of mechanical-hydraulic type, while fuel dosing and motion direction change is mechanical.

Brakes

The locomotive is equipped with "Westinghouse" type air-brakes, additional non-automatic "Knorr" type brakes, and hand screw brakes. Wheel sets are stopped one-sided by cast iron blocks.

Body

The locomotive has a chasis with two axles and welded frame. Bushing bumpers, screw and air couplings are mounted to the front and back of the frameThe body of the locomotive is composed of two engine compartments (front and back) and the elevated engineer compartment in between. The compartments are welded. Engine compartments have doors on all sides, providing convenient access to all the systems inside.The engineer compartment has large front, back and side windows with hand-powered wipers. In cold weather it is heated with fluid from the engine cooling system flowing through two radiators

Equipment

The SM03 is fitted with an air-propelled sound horn, sanding device and two fire extinguishers. The electrical system (24 V) is powered from the alternator installed on the engine or from batteries.

History

The SM03 was designed for servicing locomotive parks and small and medium-sized stations. Apart from PKP, this locomotive type was widely used in industry and storage.

Introduction

The first item was produced in 1959 in Chrzanów. From 1965 this loco was also produced at "Zaodrzańskie Zakłady Przemysłu Metalowego" in Zielona Góra. The 2Ls150 variety was produced only for PKP as a shunting-line type.

Production

Present day

A few of locomotives of this class are still in operation at PKP. Many had been taken out of service and can be seen abandoned on side tracks.
