HŽ series 6112 is a class of low-floor electrical multiple units manufactured by the Croatian company Končar Group, operated by Croatian Railways (Template:Lang-hr) and the Railways of the Federation of Bosnia and Herzegovina. Croatian Railways issued an international tender for the supply of Electric and Diesel Passenger Trains to replace the old and obsolete stock. Končar Group won the tender to supply 18 EMU train sets for local Zagreb Commuter Rail network initially, with order of up to 92 trains for the entire Croatian Railway Network to be delivered by 2016. The Railways of the Federation of Bosnia and Herzegovina also initially ordered one intercity train, with no indication of the company's intentions on ordering additional units.

The prototype made its first test run at the Zagreb – Dugo Selo line on July 3, 2011.

The construction, design and driving characteristics of the low-floor electric train enable optimized operations and increased traveling comfort in regional passenger traffic in regard to the length of the route.

Passenger space is uniform along the entire train, without partitions and stairs. Floor height is optimal for 550 mm high platforms. The train has up to eight doors on each side, which enables the rapid exchange of passengers, and an air-conditioned passenger compartment and driver's cab.

The main frame is a four-part welded steel construction linked with joints. The body consists of aluminum sandwich panels and windows. All bogies are equipped with air suspension systems, and two side drive bogies, while three free bogies are of the Jacobs type.

Three-phase asynchronous traction motors, fed from an electronic IGBT inverter provide high acceleration at start-up and a maximum speed of 200 km/h. The steering and diagnostic system is a microprocessor system that links the train subsystems with modern communication protocols that allow for linking up to three trains into one.
