Kolster’s products are intended for customers involved in the construction and operation of railway infrastructure. The product catalog contains over a thousand items, most of which are railway traffic control devices and spare parts. We also offer refurbishment of many of them. We specialize in mechanical and electromechanical devices, but we also carry out custom work. All products that are subject to certification have valid and updated certificates of approval for use issued by the Railway Transport Authority.

We develop new designs using modern three-dimensional design software (Autocad Inventor). This enables their quick implementation and modification, as well as the creation of derivative designs, and also improves our company’s cooperation with manufacturers and suppliers of other railway infrastructure components in this area. The high quality of our products and deliveries is confirmed by the ISO 9001 certificate and, what is very important to us, the positive opinions of our customers.
