I often see in the train schedules that the coaches D6 to D8 are always empty on the following trains: 22891/92 Howrah Ranchi Intercity SF Express (Via TATA), 18627/28 Howrah Ranchi Intercity Express (Via ADRA), and 12827/28 Howrah Purulia SF Express. The only time these coaches have any passengers is when the 12827/28 Howrah - Purulia SF Express returns from Howrah and the next morning from Purulia. It seems like SER should consider these coaches as general seating (GS) coaches.

Bahut baar maine notice kiya hai ki 22891/92 Howrah Ranchi Intercity SF Express (Via TATA), 18627/28 Howrah Ranchi Intercity Express (Via ADRA), aur 12827/28 Howrah Purulia SF Express ke chart preparation mein D6 se D8 tak ke coaches hamesha khali chalte hai. Jab 12827/28 Howrah - Purulia SF Express Howrah se lautati hai aur agle din subah Purulia se nikalti hai, tab in coaches mein adhiktar UR passengers bhare hote hai. SER ko in coaches ko GS coaches ki tarah treat karna chahiye, jaise ki D6, D7, D8.
