A train with subsidised 3AC fares (Garib Rath) is overtaking a train (Goa express) which is infact now a semi AC express coz of rake standardization and passengers in AC coaches are paying full AC fares.
This is one of the reasons Garib Raths should be converted to AC SF trains with full AC fares. This overtake is totally unfair to a passenger travelling in Goa express by paying full AC fare.
