This number calls my cell phone up to 4x a day. 90% of the time I only get 1/2 a ring before it hangs up. The few times I've been able to answer it, it disconnects as soon as I do. It drives me crazy. I just blocked it through Verizon, but I have to re-block it every 90 days.
Using Google, it appears this phone number belongs to Amtrak.
