Add article description

HŽ series 6112 is a class of low-floor electrical multiple units manufactured by the Croatian company Končar - Electric Vehicles (Croatian: Končar - Električna vozila), operated by Croatian Railways (Croatian: hrvatske željeznice, HŽ) and the Railways of the Federation of Bosnia and Herzegovina. A total of 55 units were manufactured for Croatian Railways, with the first units being produced in 2011.

Quick Facts Manufacturer, Constructed ...

The Railways of the Federation of Bosnia and Herzegovina also ordered one intercity train, with no indication of ordering additional units. Croatian Railways operates their fleet on suburban, regional and InterCity routes.

The prototype made its first test run on the Zagreb – Dugo Selo line on July 3, 2011.[1]

The construction, design and driving characteristics of the low-floor electric train enable optimized operations and improved passenger comfort on regional services depending upon 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. Depending on the configuration, the trains are equipped with four doors (regional configuration) or eight doors (suburban configuration). All trains are equipped with air conditioning for both the driver's cab and passenger compartment.

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 160 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)

Croatian Railways operates the following subseries of the 6112:

  • Sub-series 6 112 0xx represents the units for regional services manufactured between 2011 and the first half of 2022. A total of 17 units were built.
  • Sub-series 6 112 1xx represents the units for suburban services manufactured between 2011 and 2021. A total of 17 units were built.
  • Sub-series 6 112 2xx represents the units for suburban services manufactured between the second half of 2022 and 2023. A total of 11 units were built.
  • Sub-series 6 112 3xx represents the units for regional services manufactured between 2023 and 2024. A total of 10 units were built.

Sub-series 200 and 300 appear to be slightly different than those from initial sub-series (000 and 100), mainly involving minor differences in painting schemes and the curvature of the front.

Units painted with red stripes indicate regional units, while units with blue stripes indicate units with a suburban interior configuration. The prototype units have significantly different liveries, with the regional prototype unit (6 112 001) having a combination of white, gray and a red stripe and the suburban prototype unit (6 112 101) having a design close to the current suburban sub-series livery.

All sub-series are fully compatible with each other for mutual coupling while in service.
