Customers can save £150 per couple on any three- to six-night holiday, £250 per couple on seven- to nine-night holidays and £350 per couple on holidays 10 or more nights in duration.
Sister company Amtrak Vacations will also offer a £250 saving per couple when they upgrade to a roomette or £350 per couple when they upgrade to a bedroom.
The offers are applicable for bookings made now through 18 March for travel any time in 2022 or 2023.
Furthermore, Amtrak Vacations, Railbookers and Yankee Holidays parent company Yankee Leisure Group has now become Railbookers Group.
President and chief executive Frank Marini said the decision to rebrand the group was made to "better position" the organisation as the "independent rail holiday provider we have become".
