Amtrak employee rail passes

Just booked two deluxe bedrooms Philladelphia to
Ft.Lauderdale for mid March and had a hard time acct
very few rooms available. Returning at end of March
we have to come back a day earlier than we woished
and have to take the Meteor rather than the Star which
we prefer.
My question is what percentage of room occupancy
on Amtrak trains is taken up by pass users? How
long does an employee have to work before getting
a system pass? What Gov’t. officials get Amtrak passes?

Don’t get me wrong, I am not against Amtrak workers
getting this perk. I had a CP Rail pass and used it
quite a bit
