Most of the time, you can take Amtrak's service for free except for Acela.
The discount is more for people who live in Washington DC rather than other places but you do get discounts on curises and other stuff.
free train rides for you and spouse or domestic partner
Its like 10 or 20% with stores like AT&T. The standard discounts. Maybe some discounts at entertainment venues in the big cities.
Free travel benefits for your and your spouse and children.
Great employee discounts from a variety of retailers.
The best benefit is your ability to ride trains for free under certain circumstances. You can not displace paying passengers but I really enjoyed using it when I could.
