El Proyecto Unigauge (del inglés uni- y gauge (ancho)) es un proyecto de conversión del ancho de vía de la práctica totalidad de la red ferroviaria india al ancho unificado indio de 1676 mm. Lo comenzó Indian Railways el 1 de abril de 1992, y a fecha de 2025 está próximo a su final.[1]

Las siguientes líneas fueron desmanteladas sin ser sustituidas por otras de vía ancha. Se trataba, en su mayoría, de ferrocarriles industriales, forestales, etc.
Las siguientes líneas se mantendrán en su ancho de vía original por ser ferrocarriles patrimoniales. Algunos de ellos han sido declarados Patrimonio de la Humanidad de la UNESCO.
