well reservation data in this train shows that some days it reaches WL where as other days, it has lot of availability in 2S. If extended, it might have to start from TVC after Venad, if running via ALLP, and reach TVC after JS with JS overtaking it somewhere near ALLP. The idea I guess is due to extension of Parasu, there is a stabling line available. But I doubt whether it can have PM at TVC..!
