The safety supervisor is the function that stands between the construction site and the moving train: they ensure that no one is endangered in the track area while operations continue.
What does a safety supervisor do?
The safety supervisor is responsible for securing the work site against rail operations. Their task is to implement and enforce the safety measures laid down in the Betra so that no worker is endangered by approaching trains.
They are not responsible for the construction work, but solely for the safety of the people in and beside the track. This clear separation is intentional: safeguarding must not come into conflict with schedule or performance pressure. The safety supervisor decides solely on the basis of the hazard situation, not the construction timetable.
This independence is the core of the function. It ensures that, in case of doubt, safety takes precedence, even if that delays the construction process.
Core duties
In addition comes the seamless observation of the situation throughout the entire working time. The safety supervisor must know at all times where the workers are, which tracks are being used and whether the agreed safety equipment is functioning.
Safety procedures
Depending on the situation on the line, different safety procedures are used. They differ above all in how the danger zone is separated from train traffic:
- Fixed closure: the affected track is closed for the duration of the work. The safest option.
- Automatic warning systems: technical installations warn workers of approaching trains in good time.
- Safety lookouts: a person gives warning according to defined rules where technical systems cannot be used.
The choice depends on the hazard situation, the line speed and visibility, and is part of the Betra. The higher the speed and the poorer the visibility, the stricter the required procedure.
Interplay with the other roles
The safety supervisor works closely with the Technischer Berechtigter and the switching applicant. Only when operational safeguarding, technical safeguarding and the switching state of the overhead line all fit together may work proceed. If just one element is missing, work stops.
In LND Ingenieure’s practice these authorisations often lie in one hand. This speeds up coordination and prevents responsibility from being lost at an interface between several parties, which, especially under time pressure, is the greatest risk.
Qualification and obligation
The function of safety supervisor may only be performed by someone trained and authorised to do so. The authorisation is acquired through functional training and must be kept current. Added to this are physical fitness and familiarity with the local conditions of the respective line.
Whether and to what extent safety supervision is required follows from the hazard assessment and is laid down in the Betra. As soon as workers enter the danger zone of the track and the track is not firmly closed, safeguarding is mandatory. Without it, no work may be carried out.
Häufige Fragen
What is the main task of a safety supervisor?
They secure the work site against train traffic and protect the workers in the track area from approaching trains.
May a safety supervisor stop the work?
Yes. If safety cannot be guaranteed, they are authorised and obliged to interrupt the work.
What safety procedures are there?
From warning by safety lookouts and automatic warning systems to a fixed track closure. The procedure is laid down in the Betra.
