Electrification and double-tracking renovation in Malaysia are proceeding. So, the country would think that high speed trains are not superior to renovated conventional rails in terms of speed, train frequency, and service.
But, I think it will be difficult to defeat airplanes without connecting Kuala Lumpur and Singapore within 3 hours. Considering that the distance between Kuala Lumpur and Singapore is about 400km, trains must run at more than 134 km/h.
Is it possible by renovation of the conventional railways?
