This problem existed even when GS coaches were higher. Whatever you said is ok for South. For northern especially Bihar to Delhi trains AC and non AC should at least be separated. GS, SL ka fare nhi bda skte h kyuki political parties fir halla krenge. This is gift of Lalu. Ekbar Dinesh Trivedi ji try kiya tha increase krne ka or unhe RM se hi hta diya gya. Ab almost 20 saal ho chuka h ki fare increase hua hi nhi. Isliye railways backdoor se bda rha ab kyuki unsustainable ho gya h . Ab sirf amrit bharat , vande bharat yesab hi chalega jisme normal ke upar 20% fare liya jaega.
