That is an exceptionally long route and barely needed for end to end passengers. GKP-ALD is best served by an overnight train and that will continue to remain the first choice since VB will also take roughly the same time[ maybe ~30 mins or so lesser].
The shortest route b/w GKP-ALD is via Ayodhya-Sultanpur-Pratapgarh. But that route hasn't been developed yet. One ICE runs via that route but even that terminates at Basti instead of going all the way to GKP.
