60 is good for a start as many trains nearing 60 will be phased out of this category and will force zonal Railways to rush to upgrade to atleast 60, not even 10% of trains being run in country are able to cross 65kmph end to end.
Another thing is about section controlling, it's a good time to out source this job since now a days it is very much affected by politics, they can atleast start by NCR.
