On the military railway there was a lack of basic railway signalling devices, as well as indicators and distant signals which according to railway regulations should be placed along the entire line.

After the control on 9th April 1960 the railway was allowed to operate conditionally with the reservation that the railway administration was obliged to renovate the track, to make a telephone line exclusively for train signalling communication and install control, command and signalling devices. Before the introduction of these recommendations, the committee decided that: traffic on the line was to take place with speeds not exceeding 15 km/h, on curves and witches: 5 km/h. In addition, there could only be one train on the route and a train with no hand brakes could not exceed three wagons.
