It's not about mindset but the spending capacity of the individual, 600 travellers travel in GS sitting with fare of Rs 200 approx while 400 travel in ACC with fare Of Rs 600 in Uday and 280 are travelling in VB with fare I'd Rs 1000. The traveller who is ready to spend rs 600-900 I'd travelling by bus during night to attend to office in morning. If IR runs a dedicated train in night then it will have demand to fill 10 AC coaches and all 700 travellers in AC will be from Coimbatore itself while in day train is being shared with Tiruppur Erode and Salem.
