The revenues for railway infrastructure managers, are proportional to the volume of passenger and freight traffic, on the railway lines, supplemented by other revenues and subsidies. To maximize their revenues in a changing economic environment (where there is a tendency for the state to withdraw from funding), it is important to have and operate an infrastructure with sufficient capacity. In the event of inadequate track conditions, they will not only face a loss of revenue from network charges, but also additional penalty costs. One of the key elements in achieving stable, good track conditions, is to ensure that the substructure conditions, are adequate. In practice, the use of large-scale mechanized formation rehabilitation is becoming increasingly common, ensuring a sufficiently fast job and consistent quality. Another advantage of this technology is that it allows 100% of the logistical tasks of renewal, to be carried out on the railway track and reduces the amount of new raw materials to be installed. In this article, we present the application possibilities of large-scale mechanized formation rehabilitation and highlight the savings, in newly installed raw materials. The new materials have a high installed CO2 emission, thus, significantly increasing the ecological footprint of infrastructure development. The study aims to develop the methodology for reducing the ecological footprint, for the improvement of the railway network.
