Progress Rail and STA Modernize Merano-Malles Line with ERTMS Level 2

March 30, 2026

PISTOIA, Italy – Progress Rail, a Caterpillar company, in close collaboration with Strutture Trasporto Alto Adige (STA), has delivered a technology upgrade to the Merano–Malles railway line, supporting safer, more efficient, and more sustainable regional rail service in South Tyrol.

Driven by STA’s goal to modernize regional mobility while improving reliability and lifecycle efficiency, the project included implementation of European Railway Traffic Management System (ERTMS) Level 2, the European standard for train control and supervision that allows for the continuous, reliable data exchange of movement and speed information – effectively replacing traditional physical signaling. The deployment positions the Merano–Malles line as the first regional railway in Italy to adopt ERTMS Level 2.

“This project is built around STA’s operational and service goals, with our team delivering a solution designed to meet those needs today and well into the future,” said Sam Doerr, executive vice president of infrastructure at Progress Rail. “By combining proven ERTMS technology with our deep signaling expertise, we are helping STA enhance safety, capacity, and longterm value through reliable performance, lower lifecycle costs, and sustainable growth.”

The scope of work includes several integrated systems that together deliver measurable operational benefits, including a track management system (GDV) that centralizes commands, controls and emergency functions for more reliable infrastructure oversight; a train detection system (SDT) that enables continuous, realtime train positioning as the foundation of ERTMS safety; and a traffic management system (TMS) that improves traffic coordination, regularity and overall service.

For STA, adopting ERTMS Level 2 supports multiple objectives at once – improving safety and reliability, increasing line capacity, and reducing operating and maintenance costs. These efficiencies also contribute to lower energy consumption and reduced environmental impact, reinforcing the region’s broader sustainability goals.

“The ERTMS Level 2 system is the best solution for ensuring an efficient and modern regional rail service,” said Michael Prader, head of rolling stock & schedules at STA. “It is also an essential component of the Val Venosta railway electrification project, contributing significantly to improving the safety and reliability of the entire infrastructure.”

The Merano–Malles project reflects a broader national and European commitment to interoperable rail systems. More than 1,400 kilometers of the Italian railway are already equipped with ERTMS, with that figure expected to exceed 2,800 kilometers in 2026.
