Proven Alstom Positive Train Control Solutions

Technology Today for Safer Rails Tomorrow... 

For more than a century, Rochester, NY-based Alstom Signaling, and its predecessors, have delivered innovation in signaling and train control technology to meet the evolving needs of America’s freight and passenger lines.

Now, the industry faces a new challenge: A federal mandate for every U.S. railroad to have Positive Train Control (PTC) systems in place by 2015.

Alstom makes it possible for customers to meet that challenges with ACSES – the Advanced Civil Speed Enforcement System PTC system.

ACSES is:

• The 1st FRA type-approved PTC Solution in North America
• The only PTC system with a 10 year track record of successful U.S. service
• Proven to deliver safe parallel operation of transit, freight and high-speed traffic
• A complete PTC system comprising carborne, wayside and central office technology
• Available today to meet customers’ PTC deployment needs
