The Wagners are riding legally—they get help from TriMet's fare relief and assistance programs for low-income riders, which distribute $1.5 million annually. TriMet spokeswoman Angela Murphy says the transit agency has no way of tracking homelessness on its system, but noted that the number of grant applications for fare relief from nonprofits (which distribute the fare assistance to the homeless) had increased from 70 to 87 for fiscal year 2018.
