The HZ 6111-020 EMU, 25 kV ~ 50 Hz at commuter service, driving alongside the container shunting station (seen on the left) between the stations Kustosija and Vrapce on Zagreb - Dobova (Slovenia) mainline. The pictured unit is a rare representative of the class 6111 having two double pantographs.
<br>At Croatian Railways, the trailers of EMU-s and DMU-s are numerated as follows:
<br>On the front and the rear side of the unit (at this picture, the rear side is spotted) a unique number is found, in this case 6 111 020, while on the sides of the trailers one can observe the full UIC numbers, beginning with the 98 78 (= traction unit for domestic utilization of the Croatian Railways), followed by a number 4, 5 and 6 for each trailer. The other digits remain the same.
<br>In the considered case we have:
<br>98 78 4 111 020-6
<br>98 78 5 111 020-3
<br>98 78 6 111 020-1.
<br>The digits separated with hyphens are check digits.
