Official, or unofficial, the train does stop at Tirur every time it passes through. Even today, 25/05/2013 , it has arrived at oo-17 hrs and departed at 00-25 its sheduled departure time at least as per printed time table of SR which is in vogue. If it was an unofficial halt, the train does not have to wait till its sheduled departure time.!! p.v. hariharan
