That slight late may happen @ MGS, many a times, as u cant control 10-15 mins ARR for both train!!
The track which HWH Raj was running & stopped, is loop track while GHY Raj was on Main Track....Both train simultaneous move would have kept one train Idle @ outer...And bth got starter approx same time, with GHY Raj been further side, moved on Main Track but must have been idled @ later station to make Raj sync run...HWH Raj-GHY Raj-SDAH Raj.....
