and i didn t feel anything at all. the train bucked a little bit and came to a stop and people were a little bit nervous. i knew there was a severe enough bump that i wasn t going to get to work on time but when the smoke started filling the car and people started filling in from the back cars, i realized it was probably a little bit more serious. they broke the emergency exits and we all filed out. people were just milling around on their cell phones i guess trying to get home and get to work. my plan was to just check in, tell the conductor that i was a doctor, if anybody had any cuts or scrapes. but when i reached the back of the car i realized that the damage was a lot more severe and people were falling and filing out of the middle car pretty badly bloodied. that s when i realized it was a little bit more serious than what i expected. i told one of the other bystanders that i was a trauma surgeon and if there was anything i could do to help. he directed me into the third car where
