** After Mum-Ahm HST route is commissioned (in phases, say by 2024-28) and operationalized, the signalling, operation & maintenance practices of HSTs shall gradually percolate to rest of IR network.
** Still, the integration of HST network is not be possible with existing rail network due to adoption of standard gauge employed for HSR. If BG is adopted for HSR, a sizable traffic can be attracted on HST route by running chaircar/ overnight sleeper trains to other destinations on the IR conventional network. Such HSTs trainsets (chaircar as well as sleeper versions) shall operate at 320kmph on HST, 160/200 kmph on SHS routes (planned), & 130kmph on remaining IR network. Here the IR network maintenance standards need to be raised to meethe...

** Development of trainsets for BG may take an additional year, which may at the most delay the project by 1 year or so. Actually that is also not a probletrack tracj construction itself is getting delayed due to delays in land acquisition.
