The Sri Lanka Railways M4 is a class of diesel-electric locomotive manufactured in Canada by Montreal Locomotive Works. Fourteen of the manufacturers' model MX-620 were imported in 1975.
This was the longest locomotive in the Sri Lanka Railways previously. All units are still operational. Normally they are not used beyond Polgahawela on the main line. Usually not going upcountry now. But have gone there regularly until the previous decade.
They are painted in a livery of dark blue, light blue, silver with yellow striping; although No. 752 Point Pedro was painted in a special ICE livery.
