What is it? The Indian Railways has floated a global tender for conducting a pre-feasibility study on building a high-speed rail corridor connecting Delhi and Amritsar via Chandigarh.

So, why are we writing about this? Because, the pre-feasibility study is the first step towards launching trains that run at 200-340 kmph.
What are the challenges? In India, high-speed corridors will have to be fenced or elevated; so costs will rise exponentially. The problems of land acquisitions are also well known.
