Rewari i think can get only link trains from Rohtak and Bhiwani to Chandigarh.
Jaipur Hisar express departure from Jaipur can be moved to 2100 PM instead of 18.40 PM.. subsequently Hisar arrival will then be around 5.45 AM instead of current 3.30 AM.
This...
more... will ensure Rewari Departure on route becomes around 3 AM and Bhiwani arrival around 4.30 AM.
Ekta's departure can be moved to 5 AM from Bhiwani to ensure link with passengers coming from Rewari, Kosli, Dadri.
Ekta can still reach Kalka @ 11 AM and Ambala cannt @9.30 AM with a 5 AM departure from Bhiwani, the slack between Bhiwani and Panipat section will be eliminated that ways.
