T conductors turn to iPhones for updates

When a commuter rail train is delayed, riders with smartphones often know more about what is happening than their conductors, armed only with ­radios.

Not anymore. Twenty-four conductors, banned by federal and MBTA rules from ­using or even carrying phones, are now armed with Conductor Companions, specially programmed iPhone 4s that cannot send texts or e-mails, download applications, browse the ­Internet, or make calls, except to 911.
