Personally, I can rest in a comfortable bullet train at most for 10 hours.Can someone tell me if it will be feasible to have HSR from karachi to lahore. or is the distance to long for it to be an effective HSR, as i think anything longer then 2/5 or 3 hours of travel will be too long for people to use it.
So would it be better to connect Karachi HSR to south of punjab say Multan and then have a line from Multan to Lahore.
And surely HSR from lahore to RWP and ISB makes alot of sense as it can cut down car journey travel as thats normally the way people travel to lahore.
Generally speaking, a corridor of at most 1000-1500km is very optimal.
In China's case, the most profitable corridor is Shanghai-Beijing(1300km), last year the ridership is over 100 million.A high-speed railway has numerous stations every 10-50km, so it will have huge impacts on local economy and regional integration.
For different corridors,there are different strategies, i.e., speed, distance between stations, connectivity to urban regions, etc.
I don't know the case in Pakistan. I suggest for corridors longer than 1000km, upgrading old railways to 200km/h-250km/h is better. For high-density regions, a new 500-800km 250-300km/h high-speed railway would be very convenient, every 5-15 minutes a bullet train.
