Delhi metro commuters are always in a hurry and DMRC realises that. Apart from the emergency stop button, the DMRC escalators also have a sari guard feature that deflects loose clothing from getting trapped.
The Delhi Metro network consists of a total of 200 trains covering a total distance of 69,000 km every day. To put things into perspective, the earth's total circumference is 40,075 km!
An NGO, Salaam Balak Trust, runs an orphanage at Tis Hazari for the DMRC. It is aimed at helping street children have better futures.
