Just heard/saw this pointed out: Ten ride tickets on the Pacific Surfliner, San Joaquins, Heartland Flyer, and Cascades between Eugene, OR and Portland, OR are transferrable between passengers (though they must travel together and the named passenger must be one of them). Discounts on the Surfliner with this average 40-42% (and up to 55%) so this would be a pretty significant discount for any familial or business travel. Helpful to know, and perhaps not well known, especially if you're in a position to do planning for intrastate business travel.
