Crotram is a Croatian consortium of two companies, which produces the first Croatian low-floor tram (the TMK 2100 and the TMK 2200). It consists of Končar and TŽV Gredelj, both from Zagreb. Although theoretically both companies are of the same importance in the consortium, Gredelj produces only 13% of the worth of the tram, producing only bodies for the vehicle, and Končar made general projects for the tram, electrics, electronics, and final assembly. Initially, Đuro Đaković factory was also the part of the consortium, but they have eventually left it soon after the project started, and the development and production of hydraulics and bogie mechanics was transferred to German companies SAMES Hydro-Systemtechnik GmbH & Co. KG^[1] and Henschel Antriebstechnik GmbH.^[2]

TMK 2100

TMK 2100 is a tramcar vehicle produced by Croatian companies Končar and TŽV Gredelj, between 1994 and 2003, using parts from TMK 201. The prototype was made in 1994, and serial production began in 1997. 16 trams have been ordered and delivered for the City of Zagreb.

TMK 2200

The TMK 2200 (also known as NT 2200) is a low-floor tram that operates in Zagreb, the capital of Croatia. ZET (tr. Zagreb Electric Tramways, the city public transportation company), ordered 70 vehicles in 2003 after Crotram consortium won the tender on the ground of lower price, competing with offers by Siemens (Combino) and AnsaldoBreda (Sirio).
