Balise LifeCheck: the preventive balise maintenance tool

1 448 vues

Publié le

The Balise Life Check is a preventive balise maintenance tool, which equips diagnostic trains.
It is a moving laboratory, automating the balise maintenance. The Balise Life Check is able to produce extremely detailed signal quality information when it passes over a balise. In the past, such signal quality information was only available when sending the balise to laboratories. More products in www.ertmssolutions.com
