BPL Shatabdi does 150kmph since ages and with no fences, but IR wants protective fence for Gatiman tipped to do 160kmph.
I wonder the change in security concerns for meager 10kms bump in speed

Sir . That is a long term investment and permanent infrastructure being mandatory for ever higher speeds in future trains . MEGLEV must have been in mind while this decision must have been taken .

MEGLEV is a too distant dream Sir,
i hope they take advantage of full fencing of the tracks and give mps bump till 200kmph to Gatiman !!

Dear Sir . VACUUM SUCTION ENABLED MAGLEV TYPE TUBE ENCASED TRAINS travelling at about 7000 ( yes seven thousand ) are already in R & D stage in USA , Europe & Japan and definitely these will see light of the DAY surely one day . Afterall DREAMS ONLY DRIVE REALITIES . And DREAMING IS EVERYONE's RIGHT . And Why Not ?

Maglev trains run on a totally different kind of tracks ( not on rails, but elevated corridors), so these infrastructure upgrades are only for future increase of MPS on these sections.
The Hyperloop project is actually in development in US now, but note that such projects have a very, very high initial capital cost, ( more than 10 times the cost of a conventional rail system) and though it is a very innovative idea, it is not suitable for Indian conditions with our high population density and different requirements.
