On second stamp you can see Diesel-electrical Motor Train DEV I. The construction of the first aluminium train was instigated by Milan Holjevac, an engineer and the Director of Gradska željeznica Zagreb that was operating on the Samobor Railway from 1950. The train's drive was combined and realised with a four-stroke diesel motor with six cylinders of the FR type and the 140 KS power manufactured in the Famos factory in Sarajevo and electrical engine motor manufactured in the Končar factory in Zagreb. Due to its attractive appearance and aerodynamic shape, the aluminium trains got their popular nickname – Silver Arrows. Three years after the transport was abolished on the Samobor Railway, in 1983 all four aluminum train compositions were disassembled. Only one motor wagon in a very bad state managed to escape the scrap yard. Train length is 46.1 m, width is 2.5 m, height is 3.3 m, mass is 42.2 t, the greatest axle load bearing is 5.5 t, and the highest speed is 60 km/h
