On 21 May 2017, the new Siemens Charger SC-44 locomotives to be operated on Amtrak's Cascades service were unveiled to the public at Seattle King Street Station. The 200 km/h locomotives comply with Tier 4 emission standards and are significantly more fuel-efficient than the locomotives currently in operation. Currently undergoing extensive testing, the locomotives are scheduled to enter service this summer.
