There are several types of tickets: one way, round trip, peak, off-peak, AM peak or off-peak senior/disabled, peak child, and off-peak child. On off-peak trains, passengers can buy a family ticket for children who are accompanied by an 18-year-old for $0.75 if bought from the station agent or TVM, $1.00 on the train. Senior citizen/disabled passengers traveling during the morning peak hours are required to pay the AM peak senior citizen/disabled rate. This rate is not charged during PM peak hours.
