Locomotive manufactured in 1925 by Henschel and sons in Kassel (Germany) with the number 20605 to haul a considerable load at reduced speed, which is reflected in the small diameter of its wheels. Restored by the Vapor Madrid Railway Initiatives Center Association, which rescued it in 1990 from a scrap metal warehouse in La Felguera (Asturias). Currently in service as a historic train on the so-called Arganda Railway.
