US-based Wabtec Corporation has signed contracts valued at around $16.6m with Alaska Railroad Corporation for the supply of Positive Train Control (PTC) equipment and services.

The contract covers delivery of Interoperable Electronic Train Management System (I-ETMS) equipment and installation of all PTC components for 54 locomotives.

Wabtec Corporation chairman and CEO Albert Neupaver said: "PTC continues to be developed and deployed by freight and passenger railroads in the US, and this project with Alaska Railroad demonstrates the variety of capabilities we have to assist our customers."

"The computer-aided dispatch and back office systems will be installed on the railroad’s controlled track spanning 525 miles and are used for both freight and regularly scheduled passenger service."

Wabtec will also deploy its Train Management & Dispatch System, which is a computer-aided dispatch system that is used for centralised traffic control and track warrant control for all territories; as well as integrating I-ETMS with Wabtec’s Back Office System.

The computer-aided dispatch and back office systems will be installed on the railroad’s controlled track spanning 525 miles and are used for both freight and regularly scheduled passenger service.

Alaska Railroad Advanced Train Control Systems and Technology vice president Eileen Reilly said: "Wabtec understood our needs and delivered the computer-aided dispatch that is the cornerstone of our PTC project. We look forward to our continued successful relationship as we implement the I-ETMS PTC at the Alaska Railroad."

The Alaska Railroad system will become completely interoperable with the implementation of PTC systems by Class I railroads in the country.
