This is the best train to travel from GKP to SC. It has same timings as GKP-YPR and GKP-SC SF but while they are mostly delayed by an hour or more at SC, it is mostly at right time or sometimes even early at SC(plus you are saved from paying additional SF fare). But the train isn't same till YPR as it takes 6 more hours than GKP-YPR SF but is punctual and mostly early throughout journey.
