Yahi point me bhi mention karna chahta hu, but unfortunately aisa hone wala hai. 8 April se 02107/02108 will be regularised and renumbered to 22121/22122.
LTT SNSI kuch aise operate hogi
Thursday night departure from LTT, early morning arrival at SNSI, morning departure from SNSI and afternoon arrival at Friday.
So almost 24 hrs are avaiable for maintainance before departure of 22121.
