Riding with children

Children love buses and trains! Sound Transit wants your ride to be as enjoyable as possible, so here are a few pointers.


Children under six ride free with a paying adult on Sound Transit buses and trains. Youth ages six to 18 pay reduced fares. (The exception is Tacoma Link, which is free for all passengers.)

  • ST Express buses: $1.50 (one county) or $2.75 (multi-county)
  • Link light rail: $1.50
  • Sounder trains: between $2.50 and $4.25 (depending on distance travelled)

Helpful hints

  • Stick together! Hold hands and board as a group so no one is left behind.
  • Especially on Link light rail, the doors open for only a short time. Be prepared to board and get everyone settled quickly.
  • Link light rail trains and most ST Express buses have level boarding, so you can roll a stroller directly onboard.
  • Sounder trains and some ST Express buses have a couple of steps up to enter the vehicle, so it's easier to fold your stroller and carry it with you.
  • Do not store strollers in wheelchair or senior priority seating areas.
  • Do not block aisles and exits.
  • Covered drinks (including baby bottles) are OK. Eating is not.
  • Sounder trains have small restrooms and water fountains.
