Im re-posting here my comment on Chasing the metro -blog, from 2012: It is great to see the development and expansion of Delhi metro network. However, there are few fundamental design problems in Delhi metro layout: – Overcrowding of yellow line – No direct interchanges between major lines – Too small platforms and walkways at interchange stations (Rajiv Chowk, Central Secretariat, Kashmere gate) – Horizontal, non-center directed red line – Violet line ending abruptly in wrong location should continue at least to Karol Bagh – Lacking passenger flow management on stations The major problem is that the yellow line gets over crowded, as it is the only vertical link between the long red, blue and violet lines. There is no direct interchange from blue line to violet line, or from red line to blue line, or from violet line to red line. All interchanges must happen through the jam-packed yellow line. The north-west to north-east red line seems illogical. People both from west and from east will primarily want to travel to central Delhi, but the red line does not provide direct connectivity. Almost all passengers have to change to the yellow line. In the most successful metro lay-out designs in the world, much thought has been put in providing easy exhanges. Great examples are for instance Prague metro, and St. Petersburg metro, in which there is direct interchange provided from each of the lines to all other lines. There is no need for making two interchanges anywhere in the network, contrary to Delhi metro. In London metro and New York City metro there has been much emphasis on providing cross-platform exhanges. Please see the wikipedia link [1]. At the interchange stations (Rajiv Chowk, Kashmere gate, Central Secretariat), the platforms and passenger walkways are too small and narrow to allow smooth passenger movement and heavy congestion and uncivilized behavior results. Also, there is no proper segregation of passangers walking to and from the platforms on the walkways, causing the passenger flow rushing to the approaching train has to cross through a flow coming from opposite direction. From the metros that I have visited, I noticed Prague metro handling this particularly well.
