Croatian TMK 2200
Interior

Crotram is a Croatian consortium of two companies, which produces the first Croatian low-floor tram (the TMK 2200). It consists of Končar Elektroindustrija d.d. and TŽV Gredelj d.o.o., 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 2200

The TMK 2200 (also known as NT 2200) is a 100% 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 AG (Combino) and AnsaldoBreda, S.P.A. (Sirio).

The first batch of vehicles was delivered, as the contract requested, from May 2005 until June 2007. Satisfied with the quality of the trams, ZET ordered another 70 vehicles in mid-2007, which are due to be delivered by May 2009. All 140 vehicles ordered by ZET are 32 m long, 5-part version, but ZET have also announced a purchase of 60 shorter (3-part, about 21 m long) trams of this type.[3]

The price of the second batch is €130 million (€1,85 m. per vehicle) and is somewhat higher than price for the initial 70 ordered in 2003 (€112 million). However, due to lower production costs the increased price is still very competitive compared to Western European equivalents, which are priced up to €2,5 million each per similar vehicle.

Other transport companies also have been interested. International interest in purchasing the TMK 2200 series tramway exists. Although Croatian press articles suggested many operators being seriously interested for the purchase, more concrete arrangements since now have been:

  • Łódź Regional Tram project, for which the Crotram won on public tendering, but it was eventually annulled and Polish PESA won the repeated tender
  • In September 2006 an arrangement was made with Belgrade authorities to bring one tram for trial, but the arrangement failed
  • In 2007 HKL (Helsinki City Transport), Helsinki, Finland showed interest for the TMK 2200. Končar sent one of ZETs vehicles (Nr. 2263) to Helsinki on 5 December 2007. The HKL need to acquire new trams in order to meet the requierements of the growing track lineage as well as to partially replace the Valmet Nr I trams dating from the 1970s,[4] and TMK 2200 is one possibility among several others. HKL has some bad experience with their present low-floor Bombardier Variotrams.[5] In practice a shortened version of the TMK 2200 would have to be created if HKL were to order trams of the type. In test service the TMK 2200 received criticism from the public for not having enough seats or leg room, as well as being noisy.[6]
  • In 2008 authorities of Zagreb agreed with authorities of Sofia, Bulgaria to bring one of vehicles for trial. In October 2008 vehicle no. 2282 was sent to Sofia.

Technical

The tram is 32 meters long, with three bogied and two fully suspended articulated sections, but the modular construction allows longer and shorter versions using the same design of the sections. Wider body and standard gauge versions will also be available for construction.

The tram is entirely guided by synchronous computers. Suspension and articulations are run by hydraulics. Maximum speed is electronically limited to 70 km/h (43 mph), and the trams are equipped with air-conditioning and CCTV cameras.
