Any official source??
Further in my opinion, if it will be going via Jaipur-Sikar (after GC) then it will be Ok, but if taking Phulera Ringas Sikar route, then one thing must be considered first that the first connectivity of Jaipur with RMM is more important than Sikar etc.. So if it is getting extended to Hisar than it must run via Jaipur in any case by taking Jaipur Sikar aur Jaipur Rewari route.. connectivity of Jaipur with RMM is much more important..
