Currently, anyone under 21 can get VRE tickets for half-price, so it’s not too hard to imagine a number of 20-somethings are getting away with paying less than they should. There will have to be a public hearing before anything more happens, but VRE is proposing raising the age of children who ride for free when accompanied by an adult to 10, up from 6, in order to make up for the change. The commuter rail agency estimates eliminating the youth discount could generate $300,000 per year.
