About us

Grupa Azoty KOLTAR Sp. z o.o. is wholly owned by Grupa Azoty S.A. The company was established on January 1st 2000 following the transformation of Zakład Transportu Kolejowego, a railway transport business unit which was then part of Zakłady Azotowe w Tarnowie-Mościcach S.A.


Initially, the company’s business consisted only in maintenance of the rolling stock and railway siding of Zakłady Azotowe w Tarnowie-Mościcach S.A., but as the company developed, it started to provide services to external customers. Currently, with its competent staff, and licenses and certificates issued by relevant authorities, KOLTAR is a valued provider of railway services throughout Poland.

It is one of the few organisations in Poland to have licences required to perform comprehensive repairs of rail wagon chassis and tank wagons suitable for transport of dangerous goods by rail according to RID.

The company’s operations are supported by a Quality Management System compliant with the ISO 9001:2008 standard and the Safety Management System.

KOLTAR focuses on quality, safety and customised services. The company’s key strengths include dependability and reliability, as evidenced by the awards and distinctions received in the recent years.
