Pat Monahan of Train is promising fans of Train a big surprise on Monday, Jan. 9, but as of now there's no clue as to what the surprise is all about -- just a video teasing it!
In the video Pat encourages you to RSVP on the band's Facebook page and to check the website on Monday.  There is some speculation as to what the big surprise could be, because while Train toured with Maroon 5 last summer, Pat was working on new songs for the band.

So Train could be ready to reveal a new single, the entire new album, tour dates or something all together differently!  Looks like we'll be watching Monday with you!
