Project Unigauge


Project Unigauge, started on 1 April 1992, is an ongoing effort by Indian Railways to convert and unify almost all rail gauges in India to broad gauge.

These lines were dismantled without a broad-gauge replacement. These were mostly industrial railways, forest railways, etc.
  1. – Pani Mines
  2. – Lunavada
  3. – Velavadar
  4. Than – Chotila
  5. Victor – Dungar Junction
  6. – Toda Rai Singh
  7. – Agar
  8. – Chandan Chauki
