Transcontinental railroad train timetable 1870's

I was doing some research about the Union Pacific in the early 1870's, specifically the route through Wyoming. The main question that I have and haven't been able to find an answer to is: how often did a train run through going either East or West? Once a week, or more or less frequently?
