Indian Railways — mismanagement in running train

Address:

New Delhi, Delhi, 11027

I was travelling from sri ganganagar to delhi by 12456 train reached in time at shakurbasti station and schedule arrlival was 7.20 am in morning. From shakarpur train took 1hr 45 minutes to reach sarairohila which is just 6.8 km.
Moreover the online status was showing that train reached on time

I had to attend an important meeting and i have been issued an explanation call
Infact all passangers were telling that its normal practice. This is the status of your superfast train.
