- Original Bullet train Plan envisaged Ahmedabad-Mumbai-Pune route. But Mumbai-Pune stretch was dropped because construction cost of 320-350 kmph HSR route in this hilly stretch is prohibitive. RRTS with envisaged operating speeds of about 160 kmph may not be very costly.
- RRTS is meant for constructing stations at shorter intervals and a bit long distance (upto 150-200km) suburban type traffic.
- RRTS shall facilitate creation of new smart cities which shall act as counter magnet to the highly congested Mumbai.
