Yes the derailment is very similar to HWH Rajdhani derailment in Rafiganj..only diff I'd in Rafiganj Rajdhani fell into dry river bed..but here Shiffung Pass broke the steel girders & fell into waterbed.It'll take min 5 days for making Up line operational.As the bridge is totally collapsed.Good thing is Down line is almost 700 metres away & traffic is presently moving through single line.
