Rail Parishad, a Nashik-based NGO in Maharashtra, undertook a campaign of sending letters with suggestions for improvement to the Ministry of Railways. In 2015, the organisation mailed 150 such letters with 150 suggestions in 150 days. The letters suggested measures to provide better security, improved facilities, cleanliness, quality food and other services to passengers. The NGO claims that over 50% of its suggestions have been accepted by the Railways.
