what is it?

NMBS/SNCB Classical twin EMUs (also referred by their construction year – AM39 for "Automotrice 1939" up to AM79 for the last units from 1979; or MS39 to MS79 for the Dutch-language equivalent "Motorstel") were electric multiple unit trains operated by the National Railway Company of Belgium (NMBS/SNCB). They were the standard equipment for local trains under the Belgian standard 3000 Volts DC overhead lines, until they gradually replaced by the Class 08 Desiro Mainline EMU's starting from the early 21st century. Classical EMUs were originally painted in dark green, with small yellow stripes surrounding the front lights.
