Was a good concept, but literally not for garibs. They still overcrowd the toilet class! Garibs who travelled GR carried electric kettles to make tea and heat up other items of their food. Still do. 110V DC kettles are available online but garibs won't buy them, leave travelling in GRs. No IR employee books (themself or their families) in GRs. They all want A2 or upper class (Raj/Shat/Duronto/Tejas) but not HS.
Fingers crossed. No GR (81 3AC) coaches will be made anymore. The concept will die, slowly.
