According to the CTA, the decorative train tradition began on the Blue Line in 1992, when a “Seasons Greetings” sign was put on an “out of service” train used to deliver food to area charities.

As time went on, the tradition evolved from a simple sign to a one-of-a-kind spectacular sight to see.

After catching a glimpse of Santa riding on the outside on a special train sleigh, riding on the inside is a train-car size holiday party, with every inch of the cars covered in decorations. Including the seats.

Inside, elves hand out candy and spread holiday cheer while holiday music is played in speakers. Lights twinkle throughout the train, putting everyone in the holiday spirit.

The fun stuff isn’t just limited to train travelers. CTA bus riders will be able to have fun on the CTA holiday bus that makes its way through several city stops.
