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.
