Metrokink and the city of Santa Clarita launched the “Light Up Main Street” event by showing off the newest Tier 4 locomotive, set to run on the Antelope Valley line.

The Tier 4 was on display at the Newhall Metrolink station at 24300 Railroad Ave, where residents were able to go see the locomotive and take pictures.

The new train is the cleanest, most powerful and safest diesel locomotives in the nation, according to a Metrolink press release. It is designed to reduce the carbon emissions produced by Metrolink vehicles by up to 85 percent, as the Tier 4 trans begin replacing older models.

When all 40 of the Tier 4 locomotives are in service, officials said, it will be equivalent to stopping the annual emissions of 31,320 vehicles.

The South Coast Air Quality Management District helped fund the purchase of the Tier 4 locomotives with a grant of $111 million. The remaining projected cost of $280 million to acquire the 40 Tier 4 locomotives came from a combination of Metrolink member agency contributions and other subsidies.
