Working on the Railroad

There was a lady Sharon Carlquist's is a conductor for the Metro-North Railroad, and there is thousands of passenger lines use in New York, and Connecticut. Sharon say she does what ever strikes her fancy. Carlquist was working at southbound train and it was headed to New York City on Sept 11, 2001 and she said that her train was on top of New York Grand Central Terminal and she heard that some terrorists just flown in to the World Trade Center. to me i think that being a Conductor of the railroad must be hard and mybe you have to have alot of experience to do the job.
