Trains #11 and #12 are more trams. Train #13 is this handsome, modern EMU from Zagreb to Volinja (and return to Sunja) pictured here at Volinja. I'd have liked to have gone further and crossed the border into Bosnia-Herzegovina, but guess what? There aren't any trains. No #crossborderrail for me @jon. The onward line across the river Una to Bosnia is on the left beyond the train.
