The attorney for the engineer who was at the controls when an Amtrak train crashed in Philadelphia says his client has no recollection of a crash that killed at least seven people.

Appearing on ABC's "Good Morning America" on Thursday, attorney Robert Goggin says Brandon Bostian remembers attempting to reduce speed as the train entered a curve before he was knocked out and sustained a concussion.

The lawyer says the engineer does not remember deploying the emergency brake. Goggin says Bostian told him the last thing he recalls is coming to, looking for his bag, retrieving his cellphone and calling 911 for help.

Investigators have determined the train was traveling at 106 mph on Tuesday night before it ran off the rails, where the speed limit was 50 mph.

The lawyer says his client's memory could likely return as the head injury subsides.

Cranes and heavy equipment are working to right the overturned cars from an Amtrak train that crashed in Philadelphia, killing at least seven people.

Investigators have determined the train was traveling at 106 mph Tuesday night before it ran off the rails along a sharp curve where the speed limit drops to just 50 mph.

The National Transportation Safety Board says the engineer applied the emergency brakes moments before the crash but slowed the train to only 102 mph by the time the locomotive's black box stopped recording data.

The engineer refused to give a statement to police.
