Transmontana represents the first loco with asynchronous traction motors, successor of a series of locomotives manufactured by Softronic. This new locomotive combines Softronic’s experience in modernization and manufacture of locomotives with innovations systematically oriented to customers benefit and cost effective.
Transmontana is the most advanced electric locomotive made in Eastern Europe owning approval certificates by the Romanian Railway Authority and by the National Transport Authority from Hungary and is registered at the 2014 ERA (European Railway Agency).
Co’-Co’ wheel arrangement, equipped with an advanced power system working with both 25 kV 50 Hz and 15 kV 16.7 Hz, is powered by six asynchronous motors developing a total power of 6.000 kW capable of providing speeds of up to 200 km/h.
The locomotive uses new developments adapted to new requirements: a new body, special asynchronous traction motors, regenerative braking, electronic power converters with IGBT, unit converter, electronic equipment for command and control, LED lights and many others.
For LTE-group Transmontana type locomotives can be seen on the railways from Romania and Hungary.
