How Delhi metro dug deep for its smallest stn

NEW DELHI: It took out-of-the-box thinking to tide the problem of space confronting Delhi Metro Rail Corporation within the construction of the station at Ashram in south Delhi. DMRC came up with a singular design that included an additional ground to accommodate passenger spaces and utilities.

Located below probably the most city’s busiest site visitors junctions, the Ashram metro station is exclusive but even so being micro-sized.

Only 8 metres of air nozzles are present at the platform degree as an alternative of the standard 40, and the two tunnel air flow fanatics are placed one over the opposite around the tracks at concourse and mezzanine levels, attached with each different and the tracks by means of vertical plenums. This is the primary time DMRC has attempted a gadget like this.


The respectable additionally disclosed that the auxiliary sub-station, which is typically positioned at the platform degree, has been shifted to the concourse. And not like in different underground stations, only one aspect of the concourse space is open to passengers, the opposite being occupied by means of the station keep watch over room and application rooms.
