Abstract
The revenues of the railway infrastructure managers are proportional to the volume of the traffic on the railway lines, supplemented by other revenues and subsidies. To maximise 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 condition is to ensure that the formation conditions are adequate. In practice, the use of large-scale mechanised subgrade rehabilitation is becoming increasingly common, ensuring a sufficiently fast job and consistent quality. Another advantage of its technology is that it allows 100% of the logistical tasks of renewal to be carried out on the track and reduces the amount of new raw materials to be installed. In this article, we will present the application possibilities of large-scale mechanised subgrade rehabilitation and highlight the savings in newly installed raw materials. With this thought-provoking article, we aim to raise the interest of the professional audience to learn more about this technology.
