# An innovative automatic track warning system

![An innovative automatic track warning system](https://www.systra.com/wp-content/uploads/2022/08/chantier-1-scaled.jpg)

The new automatic track warning system (ATWS) co-developed by SYSTRA and Zöllner
provides a response to the increasing safety requirements for work on railway
lines

.

Existing solution with look-outs have their limitations. They require
significant human resources, sometimes even greater than those necessary for the
work, and are difficult to mobilise at any time of the day. They are also costly
for the operator, as maintenance and regeneration work is often carried out at
night due to the density and pace of daytime traffic.

## Operational efficiency and simplicity of deployment

The new automatic audio and audible and visual warning system co-developed by
SYSTRA and Zöllner is a simpler and a more efficient solution than existing
systems.

The system does neither require any modification to existing stations and
signalling systems, nor does it require cabling or the installation of detection
equipment in the field prior to operations. It can be deployed on any line
equipped with ERTMS Level 2 worldwide. Several warning modes are possible
depending on the type of intervention and the requirements of the maintenance
sites: trafficked track, contiguous track. This system requires only one
operator.

## Benefits for rail infrastructure managers

The new system also offers significant benefits to railway infrastructure
managers:

- Improvement of the overall safety and working conditions of the agents
- Reduction of the costs of future regeneration operations
- Facilitation of maintenance work near the tracks (vegetation) and track
  inspection
- Maintenance operations carried out without interrupting rail traffic and
  therefore less costly

In France, the ARGOS project, which aims to deploy new generation signaling
stations, will make it possible to extend this warning solution to conventional
lines. A POC (Proof of Concept), carried out with MESEA on the South Europe
Atlantic high-speed line between Tours and Bordeaux, has demonstrated the
feasibility of the concept.

**Come and visit us at InnoTrans from 20 to 23 September at the SYSTRA stand, Hall 5-2, where our experts Gilles Augot and Jean-Pierre Ponchon will be presenting this new warning system.**
