It already has 2 parking line besides the 2 pitline in the C&W yard. besides 6pfs at COA and CCT out of which 3 can be used for parking which already is being implemented - circar on pf 1 at COA, cocananda at pf 3 COA, special/bhavnagar at pf 3 CCT.
and as i recollected DSP saying construction of 3rd pitline might b gng on, i just found this on googlemaps. Adjacent to parking line beside pitline 2, we can notice a rised bund/elevation structure all along the length (length of approx 30 caoches). That might be 3rd pitline coming up.
