Indian broad gauge railways extension to Central Asia (updated)

The proposed Indian broad gauge railways extension to Central Asia:

*Pakistan-Afghan-Central Asia railway project: The proposed 1,676 mm (5 ft 6 in) Indian gauge railways between Pakistan and the Central Asian Republics through Afghanistan.
*India-Xinjiang-Kazakh railway project: The proposed 1,676 mm (5 ft 6 in) Indian gauge railway between India and Kazakhstan through Xinjiang, China which will bypass Pakistan and Afghanistan.
*Pakistan-Xinjiang-Tajik railway project: The proposed 1,676 mm (5 ft 6 in) Indian gauge railway between Pakistan and Tajikistan through Xinjiang, China which will bypass Afghanistan.
*Pakistan-Iran-Turkmen railway project: The proposed 1,676 mm (5 ft 6 in) Indian gauge railway between Pakistan and Turkmenistan through Iran which will bypass Afghanistan.

Design guidelines for the proposed Indian broad gauge railways extension to Central Asia:

*Electrification should be 2x25kV AC overhead lines.
*Passenger platform height should be 200 mm (7.9 in) above rails.
*Sleeper type should be concrete.
*Loading gauge should be 4.1m wide and 6.15m tall.
*Double-track side should be right-hand runnning.
*Minimum overhead wire height should be 6.5m above rails.
*Minimum passenger platform length should be 600m.
*Rail profile should be 75kg/m.

The Indian broad gauge railways extension to Central Asia are desireble to create multiple break-of-gauge points between Indian gauge and Russian gauge without any other gauge intervening.
