Rakes are not rotated generally, they have hidden RSA which took place only in the case of major delay, Specially in winter season where all trains used to run with delays.
Direct RSA becomes visible between 12581/2 & 15127/8 and sometimes rake given to SG as well, if there is PM days and the rake is delayed heavily.
In the month of January, During the inauguration of Ballia Superfast, 12582 which is scheduled to arrive at BSBS 10:00 and later rake have to leave for Ballia for Inauguration, but train got delayed heavily...

please wait...Translate to HindiRakes ko aam tor par ghoomaya nahin jata hai, unmein chhupi hui RSA hoti hai jo keval badi der ke mamle mein hoti hai, khaaskar sardiyon mein jab sab trains der se chalti hain.
Sidhi RSA 12581/2 aur 15127/8 ke beech dikhayi deti hai aur kabhi kabhi rake ko SG ko bhi diya jata hai, agar PM din hain aur rake ki badi der se deri ho.
Januari mahine mein, Ballia Superfast ke shubhaarambh ke dauran, 12582 jiska BSBS par pahunchne ka samay 10:00 baje hai aur baad mein rake ko Ballia ke liye shubhaarambh ke liye bhejna hota hai, lekin train bahut der se der ho gayi aur raat mein Bsbs pahunchi. Fir KV ke upalabdha rake ko Ballia ke liye shubhaarambh ke liye bhej diya gaya Train Boards Mini Truck par Road ke dwara aane wale hain. Ye hota hai is tarah se.
