Railways to run AC coaches on trains with speeds between 130 - 160 kmph

As a step towards modernisation of its rolling stock, the Indian Railways is planning to convert all its non-air conditioned (non-AC) coaches to air-conditioned on high-speed routes.

At present, the national transporter is working on a plan to upgrade the railway network to a high-speed one.
