Automatic Track Warning Systems (ATWS)
The first company active in supplying and installing Automatic Track Warning Systems (ATWS), we design, install and manage track-warning devices for railway worksites on behalf of public train operators and major private companies.These systems are capable of detecting the transit of trains, in the widest variety of different layouts, and guarantee timely and appropriate individual and/or collective signaling.
 The videos below describe the two systems that we use.
The system basically consists of:
  • An apparatus that signals a train is approaching
  • A central processing unit
  • Alarm systems with sound and lights
Spotting sensors, configured at an appropriate distance from the worksite, set off a series of optical and audible signals along the entire worksite. The all-clear sensors, meanwhile, deactivate the warning elements after the train has passed by. The many possible configuration options allows you to customize the system according to the characteristics of each site, and thus to take all relevant factors into account as early as the planning phase, such as the number of tracks, the direction and speed of the trains and the presence of switches or tunnels.

As a manager of ATWS systems, we provide two different types of systems from two supplier companies:

1. Planning

The aim of the planning stage is to produce documentation that allows for the defining of the system's configuration and for its relative installation plans to be drawn up, as well as the way in which the system will be monitored and controlled.
During this phase the acquisition of design-input elements (input data), carried out by means of a fact-finding inspection, is very important.
The planning documentation supplies the following elements:
  • Distances and progressive positioning of the rail contact (warning and all-clear)
  • Size of the worksite (length) and maximum speed of the train in transit
  • Identification of control unit (serial number and expiry date of inspection)
  • Safety time
The ATWS project is developed by our designer and verified by the individual who coordinates execution of the work (CEL) who may, at this stage, work in collaboration with an ATWS designer from RFI. Validation of the project allows for the closing of the planning phase and for proceeding with the ATWS installation.

2. Installation

Installation of the system is carried out in accordance with a precise sequence that includes five phases:
  1. Preparation of the materials
  2. Installation at the worksite
  3. Internal testing (M2 S.r.l.)
  4. Delivery of materials to the worksite
  5. Training / information for employees at the worksite

3. Management

During the course of worksite operations, there will be a person who is responsible for the proper operation and efficient maintenance of the ATWS that has been installed (the ATWS manager). Once work has begun, upon perception of the ordinary warning signal, the employees will remain and machines will be kept in the safe zone, maintaining a distance from the track in operation as provided by Art. 20.1 of the RCT and as amended by Art. 2.1 a) of ANSF, Decree No. 16/2010. All tasks performed with noisy machinery must be suspended: this precaution is observed as long as the flashing light is on.
