For some unknown reason on both side this train is intentionally delayed almost every day to pass Rajdhanis.
While going to NDLS, it is stopped at Aligarh, to pass almost 6 Rajs and sometimes Duronto. Infact there are few samosa stalls just beside stations which I think pulls their major sale from Poorva every day.
During return, after half an hour it stops again to pass 6 Rajs again at a gap of 15 mins each and it becomes late by more than an hour which it hardly makes up.
In...
more... this scenario, since its a daily occurance,I dont understand, why Poorva's time is not changed and starts after Rajs from NDLS so that not only it can maintain schedule but also more people may avail this train as it shall leave NDLS 1-2 hrs later.
