Unless you start before a pick starts (and can then pick your work), you'll be on the extra list. More than likely, your days off will be during the week. Time of day work depends on the particular slot but work on the list is assigned in report time order. So slot 1 would get the first open job, slot 2 gets the second and so forth.  You can be towards the bottom (in the "PM" slots) of the list and still be assigned an AM report, as long as you have 8 hours in between work. 

Does anyone have information as to once you pass training do you work weekends nights etc right from start?

Do you guys know if Block operator and Assistant conductor classes starts on either same or similar dates?

ohhh ok gotcha. 

Classes always start on a Wednesday because the pay week for your paycheck runs from Wednesday through Tuesday. Every single one of us started with the railroad on a Wednesday.

Unless those who passed arent on the forum.. I would think I they would be all over the forums talking about it
