Rolling stock

Rolling stock – expertise for the full life cycle

Rail transport (rolling stock industry) is considered by many the transport mode of the future. Railway construction is growing around the world, both for traffic and freight. It is supported, among other things, by building more integrated European railway network and cross-border rail links, modernisation, and harmonisation of technical and safety standards. At the same time developing urban areas pin their hopes on trams and urban rail, answering urgent need to reduce pollution and improve efficiency of city transportation.

Comatec has long experience working in this industry and as an expert in extensive railway purchases and modernisations. We offer support in various projects, related to new design, facelifts or optimisation of the product, as well as customisations of constructions for particular order. We provide consulting services for the purchasing, maintenance and refurbishing of rolling stock. We assist in the procurement of rolling stock by drawing up technical specifications for calls for tender, for the assessment of offers and for the delivery control of rolling stock.
