Amtrak’s Wi-Fi service remains spotty and sluggish on many routes where it’s available, despite the company’s numerous attempts to upgrade on-train connectivity through the years. But now it’s getting serious about the challenge. Amtrak says it wants to build a Wi-Fi solution that actually works for its Northeast Corridor. It wants to build “a true broadband experience” with enough capacity and speed to let riders watch YouTube, Netflix, and stream music over Spotify without worry. With the infrastructure in place now, that’s just not a realistic possibility; Amtrak currently has restrictions in place against streaming services and large downloads.
