Diesel-electric 180 at Haarlem station

These diesels were built in the 1950s, but the streamline design dates from the 1930s. There were electric versions too of this design. The streamline and the speed of the diesels caused quite a stir in the 1930s.
Both the trains belong to the foundation HIJSM (Haarlem IJmuidense Spoorweg Maatschappij).
