The Walking Dead returns this Sunday on AMC, but they have already invaded Union Station.

Blog of the Living Dead reports that today (Wednesday) a chain-gang of zombies will be wandering among commuters, while T-shirts will be handed out on the second floor of Union between 2 and 7 p.m.

There’s already a massive rotting hand on the main floor of the station. Every day a finger breaks off and if you tweet a photo of yourself with the finger stumps and #TWDFeb10 you can win one of the broken-off digits.

In other Walking Dead news, former showrunner Glen Mazzara, who was supposed to be a part of a TV Academy panel about the show this week, didn’t show. Or was asked to stay away. Previously, Frank Darabont suddenly stopped working on the show. Deadline has more.
