After reading lot of blogs, if ALD, MGS are the biggest villains in terms of controlling the train, I guess Ludhiana can be termed as Villain of NR in term of Controlling. Fresh Example. 12919 Malwa Express was just 6 mins late ( Yes just 6 min..) till Khanna and after Ludhiana it got more then 1:30 hour late in Ludhiana. Same fate for the Prestigious 12471 Swaraj Express which was RT till Ambala, but guess.. Got more then 1 hour late. I'm not sure what the issue with Ludhiana. If Ludhiana is congested same is Amabala Junction . And this is only for Jammu bound train not for Amritsar bound. Shane Punjab never gets so much delayed in Ludhiana nor any other train.
