Art on Track, an annual art show on a Loop train, is back!

The mobile show, produced by local artist group Salvo, will run from 5-10 p.m., Sept. 17. The entrance is at the Adams/Wabash station.

One of the installations this year is the mobile garden project, founder Joe Baldwin said. Baldwin has been working for more than a year to get a garden installed on a flatbed "L" car.

Tickets to the show are available for $10.
