The Mumbai Rail Map (MRM) is a significant project designed by Prof. Mandar Rane from the Industrial Design Centre (IDC), IIT Bombay. The map was created to simplify and enhance the experience of navigating the complex railway network of Mumbai, one of the busiest public transportation systems in the world. Prof. Rane’s design provides a clear, easy-to-read, and aesthetically appealing representation of Mumbai’s intricate railways, helping millions of commuters better understand and use the system efficiently. The Mumbai railway network is spread over three major lines: Western, Central, and Harbour. Navigating these lines can be confusing, especially for new or occasional users. The Mumbai Rail Map distils this complex information into a clean, organised visual format. The map uses colour-coded lines for the different railway routes (Western Line, Central Line, Harbour Line, and Trans-Harbour Line), making it easier for commuters to identify and follow their respective routes. Prof. Rane’s design ensures that the text and symbols are legible and accessible to a wide range of users, including those with visual impairments. The use of contrasting colours and bold typefaces ensures clarity in various lighting conditions and from different viewing distances.
