Our story

Since its founding date in 1994, ALTRO has come a long way. From a small enterprise which fought for its place on the market, through a period of intensive development and finally to one of the global factors in the area of railway signalling and automatic train protection systems. In the beginning of its development, ALTPRO consisted of a group of enthusiasts led by today’s director Zvonimir Viduka, who were active in the field of industrial electronics. By collecting knowledge and experience, fueled by sheer will and love towards electronics, it soon became clear what ALTPRO wanted to be in the future – globally recognized company in the field of railways.

In its newer history, which begins by moving to new facilities ODRA 1, ALTPRO multiplies in terms of new products and in the number of employees and revenue. Today’s crown of ALTPRO’s development is the recent expansion to the new research and innovation centre ODRA 2. The investment in the new centre marked the beginning of a new era in which ALTPRO decisively advances towards its goal – to be one of the world leaders in the area of signalling technology and automatic train protection systems.
