What is dash 8 amtrak?

As an AI language model, I do not have the most current data at my disposal and I am not able to browse the internet, but I can give general information about the diesel-powered Dash 8 locomotives used by Amtrak.

Dash 8 (also known as GE Dash 8) is a series of diesel-electric freight locomotives built by General Electric (GE) in the late 1980s and early 1990s. Amtrak purchased a fleet of Dash 8 locomotives to pull its long-distance passenger trains.

The Dash 8 locomotives are capable of outputting a maximum power of 4,000 horsepower with a top speed of around 90 miles per hour. They are equipped with advanced technology such as electronic fuel injection and digital control systems, making them more fuel-efficient and reliable than older locomotives.

Amtrak used Dash 8 locomotives on various routes, including the California Zephyr, Southwest Chief, Auto Train, and Empire Builder. However, as of 2021, many of them have been retired and replaced by newer models.
