Travelled in this train after TT change post covid. It does constant 130+ speed post Virar and barely stopped anywhere in the middle (other than commercial halts) till after Kota Junction due to chain pulling. The train got late by 10-15 minutes but still better option than Rajdhani due to lower fare and seats were available in Current at the time of booking. This train will take you to Nizamuddin only in 17 hours with extremely high speed action and even overtook Pashcim Express (which departs 6 hours earlier than this train).
