It's also worth looking at which unions ratified it, for instance SMART Yardmasters and Mechanical ratified it, but TD, the branch that is on the train, have not.

IBEW? thats the electric workers union they aren't on call 24/365 to drive a train into the middle of nowhere sit for 12 hours then be shuttled to bunkhouse.
TCU, BRC that communications and car maintainance...
ATDA, dispachers
IAM, machinists
NCFO, well the Firemen and Oilers there refers to fixed plants not locomotives, and they've been part of the service industry union for the last 30 years, I don't know who exactly they cover but it's again probably not the engineers/conductors.
All of which is to say that the unions that have ratified the agreement are the ones that aren't being fucked by PTO/sick day shit (which isn't to say unaffected but, not fucked).
