On most trains and on most days, up to two children may travel at the half-price fare with each passenger paying the full adult fare. If a third child will be traveling in the party, reservations must be made for that child as an "Adult" and the full adult fare will be charged. For larger parties, make sure that one passenger paying the full adult fare is included for each set of two discounted children.
One child (classified as an "infant") under the age of two may ride free with each passenger paying the full adult fare. Additional children under age two are permitted with each adult traveler under the 50% discount policy.
An infant traveling free may occupy a vacant seat only if the seat is not needed for a paying passenger. Conductors may require that infants occupying a seat without paying a fare be removed to provide seating to a fare-paying passenger.
*Exception: A minor who is 16 or 17, who is a parent to children of any age, may bring those children without restriction. The 16- or 17-year-old must bring proof that he or she is the parent of the children.
