Also interesting...in the very early years, the train were Amtrak, "in name only"...everything to do with their operation was simply a continuation of their former railroad's operation...the equipment, the operating as well as on board service employees...even reservation's and ticketing. In fact, even the train numbers so as the SP operated TT's showed...there were more than one train with the "same" numbers, such as the Sunset and the Denver Zephyr carring number 1, at the same time. The only Amtrak employees were at national headquarter's, and a few "Passenger Service Representatives assigned to ride trains. That all changed gradually, thru the years, as the new company matured, and assumed more and more responsibility. The biggest change was in 1976, when Amtrak acquired the NEC, and became a "real railroad"...
