Almost every traveller is using it as user interface is excellent. WIMT thik hai. Normally theek hi dikhata hai. Bade slack ko to wo manage kar leta hai lekin chhote slack like 30 min to 60 min ko wo consider nahi kar pata utna sahi se aur train ka expected arrival late hi dikhata hai. Railfans can see that & deduce that, no, train can arrive early than ETA on WIMT considering MPS of route & traffic, but normal pax ko gaflat ho jaati hai, jo is jaise case mein huyi.
Plus official validity bhi nahi hai uski, as pvt app hai.
