Buying a ticket as far ahead of time as possible, when the demand is not as great, will always save you money. You can do this either online or at your local railway station.
If you are planning to take an extended trip around a continent, it may be cheaper to buy a rail pass. Amtrak offers packages of 15-, 30-, and 45-day increments for its USA rail pass as well as a 21-day rail pass for 7 days of travel within California.
If you are a student or senior citizen, you may be eligible for discounts. Everyone may take advantage of sales, which are often advertised online. Amtrak lists advertised specials and weekly specials as well as discounts on selected routes on its website.
