# Narrow-gauge railways in India

This is a list of former and current narrow-gauge railways in India. All railways except the heritage ones are closed or under conversion/are converted to the nation-wide standard 5 ft 6 in (1,676 mm) gauge, under Project Unigauge. Despite attempts to convert the entire country into broad-gauge many Metro systems and Mumbai–Ahmedabad high-speed rail corridor are done under Standard-gauge railway.
In 2007, India had 45 narrow-gauge lines in operation and most of these lines were made in pre-independence era predominantly in territories controlled by Princely states or terrain with steep gradient.
