Il-Polonja – Vaguni għas-sorveljanza u l-manutenzjoni tal-ferroviji – Dostawa pojazdu do obróbki szyn tramwajowych

Il-ġħażla tal-ordni huwa t-tella' ta' karozza għal il-ħażin tal-ħżun tramvaj.

(Note: I have translated the text into Maltese, preserving the procurement terminology, proper nouns, numbers, units, reference codes and URLs as requested. I have also translated the phrase 'dostawa pojazdu' as 't-tella' ta' karozza' to convey the meaning of 'delivery of a vehicle' in a way that is idiomatic in Maltese.)
