When Carol Hansen first started in the call center for Metro Transit — then called MTC — back in 1976, “there were no computers. Everything was paper. We had a big map on the wall, and we used a Hudson Street guide to look up addresses, and we had paper schedules to go by. Some of the calls might be 10 minutes long. We had to physically look up the address, then go to that map and try to figure it out. You got down on your knees to see the bottom of the map. Short people had to stand on a stool.
