As of yesterday, Verizon EVDO just started working in the Metro-North tunnel under Manhattan from 125th St.
I know because I’m 2 minutes into it right now, posting this. Just passed the “Exit 59th St.” sign. The connection would previously drop completely about 15 seconds into the tunnel.
Update: Platforming now on an upstairs track. Never lost the connection.
