This need/lackedge is nowadays being solved by the only possible way – the railroad tie replacement.
The replacement of the tie is disadvantageous because the break of the spike happens mostly in winter time when the number of rail failures is increased. The replacement of the railroad tie weighing 340 kg is physically very challenging.
The railroad tie replacement is complicated, time-consuming technological procedure connected with many other operations such as compacting the subgrade.
During the replacement the track has to be excluded from operation for couple of hours. It is not possible to perform the replacement during the operation. In winter months the replacement is completely excluded. During the railroad tie replacement, the disruption of geometry and stability of the track occurs and further work operations are required.
