Agents of S.H.I.E.L.D.: T.R.A.C.K.S. Clip Released Online

Marvel Studios and ABC have released a clip from Tuesday's episode of Marvel's Agents of S.H.I.E.L.D., titled "T.R.A.C.K.S." The episode description says the team is on a train headed for certain death, and we may be starting to see some of that here, as Ward and Coulson's cover is blown and they're assailed by a barrage of bad guys, while it appears as though Coulson may have had someone tampering with his drink. You can check out the clip embedded below. Marvel's Agents of S.H.I.E.L.D. returns from its post-holiday mini-hiatus on Tuesday at 8 p.m. EST on ABC.
