The OBS Chiefs lasted for many years after the operating crew became Amtrak employees.On the trains that had Chief's, the conductor's are not that "busy", most of the time. The main reason they had Chief's was that the train crew's, were still employed by the host railroads at that time, and more and more of them rotated from freight service, so they were not that cognizant of passenger crew supervision. Nor did they have that much stake in Amtrak's operation's. Of course there were notable exception's, and some did a superb job in fulfilling that part of their obligation. Hence, the On Board Chief's position was created, so that Amtrak could more effectively supervise their OBS employees.
