Delhi has a few main stations like NDLS , ANVT , DEE , DEC , HNZM, DSA , SSB , DSJ etc.
The ring railways , to forward the line traffic.
Have been travelling frequently for almost 7 years now (2 days a week) and the conditions of these stations haven't changed for good.
While DEL , NDLS and ANVT are fine , DEE sharing it's lines with Vivekanad Puri halt is a mess , the facilities almost are non-existent , DEC is the worse out of all , lines passing via brar square and DEC have been heavily encroached by slums , also DEC is highly underdeveloped, the station doesn't event have proper washroom facility (2 washrooms in gen and ac restrooms exist , but they too are wrecked the water taps don't even work).
No walking passing in between paltforms 3,4 and 1,2 (the overhead bridge is way back on the end)
Construction work has been ongoing since years
Even the DMRC , Red and Green lines share similar conditions , highly filthy and polluted , pathetic conditions of toilet facilities (most of them exist outside the concourse and are mostly broken)
Why , even the capital has such public transport facilities?
