We are an engineering office mainly engaged in technology of railway and public transport, traffic relations modeling, operational concepts and timetable design, capacity of critical infrastructure elements. We strive to find solutions that meet today’s changing conditions that will allow the infrastructure operators, infrastructure designers, carriers, public transport administrators and coordinators of integrated transport systems. In the field of microsimulation of critical elements, especially on railway infrastructure, we use the OpenTrack program - a tool for simulating railway networks, for the mutual evaluation of variants of operational concepts and infrastructure measures.
