The Board of Directors of Metrolink are scheduled Friday to vote on a contract worth up to $120 million for the installation of a positive train control system. The contract would be with Parsons Transportation Group.

The technology was created to prevent trains from colliding. Metrolink has been pursuing such a system in the wake of the deadly crash in Chatsworth in Sept. 2008 between one of its trains and a Union Pacific freight train. Twenty five people on the Metrolink train were killed, including the engineer, who was found to be text messaging in the seconds leading up to the crash.

Here’s the agenda. Metro is one of the five county transportation agencies in Southern California that provides funding to Metrolink.
