This is something which was expected.
If You checkout the satellite view of dehradun haridwar track..U will get to know the forest area..
As we leave DDN..hardly after 6-7 km forest area starts and goes upto Doiwala..and after Doiwala, most part of route is through forests.
I dont think it would be possible to run train at 100 kmph and suddenly reduce the speed...
more... to 30-35 kmph
Some solid solution is required to prevent animal run over and high speed running of trains
