That’s gonna be a lot of Tweeting.
I laughed at this, but you are correct. And this is not to poke fingers at Amtrak's reliability, but after scrolling through that Twitter feed, I'm led to believe it's basically useless in its current form. If you subscribe to this, you are going to get a constant stream of "LD train that departed XYZville on X/Y is operating __ hours late due to _______________." Interesting to rail fans, but the noise-to-signal ratio is pretty bad for the general public.
People who use Twitter are probably also using Amtrak's app, or the website itself, to check on the status of a specific train. Amtrak should save this Twitter account for incidents that rise to the level of a Service Disruption, IMO.
