In an effort to tackle widespread sexual harassment on India's railways, the authorities have introduced female-only services in four of the country's largest cities.

Packed into crowded carriages with men, women are often the victims of groping and catcalling.

The trend has worsened as large numbers of women started to join the workforce during the past decade.

As Supriya Sobti reports from Mumbai, many women say the new female-only carriages are a good start to addressing the problem.
