According to a recent post by our friends at SunRailRiders.com (website) a number of ticket validators at several SunRail stations are out of order.
According to the blog, questions were raised at a recent SunRail operations board meeting when SunRail managers said the wiring had degraded on the ticket stations and that they would need to be repaired.
The ticket validators are where riders scan their ticket before riding the train and afterward when they disembark.
