19011/19012 timings have never been changed since 25 years. In the 70's it used to arrive ADI@16:30, and thus need to be speeded up.
May be something like this might be useful:
19011 BCT dep. 06:45 / ADI arr. 14:15
19012 ADI dep. 07:15 / BCT arr. 14:45
Only...
more... Then the SF tag could be of any worth!
