SER ki train to highly demand full rahti h but har kuch to thik h but other zone k compare me updated engines aur coaches milne me bahot late hota h.
2nd reason ye bhi hai ki iske maximum trains long route k hai aur 110mps wale routes h.. .isi liye thoda late priority deta h. Abhi HWH NDLS MUMBAI route pe IR ka focus jyda h.
