I was wondering, since there introduction on Metroliner trains in 1986, has the Railphone service been popular? Has anyone ever used it? If so how did it work and how much did it cost? I didnt notice any on the Amfleets Ive seen, but are their special antennas on the car to transmit the calls? Id imagine the service is made obsolete by cell phones, but I wonder if quite a few people still use it since alot of refurbished business class cars have them like the one I rode in. I was gonna make a call but I didnt have a credit card to insert into the thing!!
