Locomotive Care

Complete maintenance solutions for locomotives and freight wagons

The first railroad in Bulgaria from Ruse to Varna was steamed from our hometown in 1866. Our factory was built near the new line to service first locomotives in Bulgaria.

Year by year we have gained the expertise to repair steam, diesel and electric locomotives. Nowadays we operate a modern locomotive care facility equipped will everything neccessary for even most complex repairs of diesel and electric locomotives, sets of EMU and DMU trains.
