I'm going to be arriving at Delhi Airport in the afternoon, and plan to take a night train departing from Delhi Cantt station (DEC).
My current approach would be to take the airport metro to Dwarka Sector 21 and walk 2.2km or take the 717 bus to Shahabad Muhammadpur Halt (SMDP), where I can catch a train to Delhi Cantt.
However, train schedule information for that line on that day isn't available (yet?), and I don't know the area. Is that a sensible plan? Can I assume the 54411 to run daily (as the IRCTC website doesn't know 5xxxx trains apparently)?
