Caltrain's approved refund policy, allows for the refund of a Monthly Pass.

Monthly Pass Refund:
An unused Monthly Pass, returned prior to the date the pass first became valid, will be refunded for the full fare paid. A Monthly Pass returned during the month for which it's issued will be pro-rated and refunded based on the remaining period of non use (the value of two one-way fares per weekday up to the date the pass is returned for refund).

One-way, Day Pass, 8-ride, Zone Upgrade tickets and parking permits are non-refundable. However, if there are extenuating circumstances and you would like to request a refund review, please download and complete the form (MS WORD or PDF) and submit it for consideration.
