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. A total of 55 units were manufactured for Croatian Railways between 2011 and 2024 (28 of which were specially designed for the needs of urban-suburban transport - meaning that the passenger interior consists of less space intended for seating and more space intended for standing, for the purpose of transporting larger number of passengers).

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. On Croatian Railways, 6 112 units can be found operating on suburban, regional and inter city level.

The prototype made its first test run at the Zagreb – Dugo Selo line on July 3, 2011.[2]

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.

Sub-series' (Croatian Railways)

6 112 series have several sub-series', as follows:

  • Sub-series 6 112-000 represents the units for regional traffic manufactured between 2011 and the first half of 2022
  • Sub-series 6 112-100 represents the units for suburban traffic manufactured between 2011 and 2021
  • Sub-series 6 112-200 represents the units for suburban traffic manufactured between the second half of 2022 and 2023
  • Sub-series 6 112-300 represents the units for regional traffic manufactured between 2023 and 2024

Sub-series 200 and 300 appear to be slightly different than those from initial sub-series (000 and 100), mainly regarding minor differences in painting schemes and frontal exterior design.

As far as livery is concerned, units dominated by blue and white side coloring are intended for suburban transport, while units dominated by red and white side coloring are intended for regional transport on longer lines. Prototype of the train, unit 6 112 001, has its own livery scheme which is dominated by white and grey colors.  

All sub-series are compatibile for mutual coupling while in service.
