The Download: American’s hydrogen prepare experiment, and why we’d like boring robots

Like a mirage dashing throughout the dusty desert outdoors Pueblo, Colorado, the primary hydrogen-fuel-cell passenger prepare within the United States is getting warmed up on its check monitor. It will quickly be shipped to Southern California, the place it’s slated to hold riders on San Bernardino County’s Arrow commuter rail service earlier than the top of the 12 months.

But it’s additionally political: a query of the extent to which decarbonization can, or ought to, usher in a broader transformation of rail transportation.

In the insular world of railroading, this hydrogen-powered prepare is a Rorschach check. To some, it represents the way forward for rail transportation. To others, it seems to be like a giant, shiny distraction. Read the total story.
