TKD WDP-4B "प्रतीक" - रंग ऐसा कि हर किसी को प्यार हो जाए - Anubhav Kashyap

Just out of Curiosity asking,
From when Balasore and Adra were converted into Regular Halts for this train ?
Last time when i checked , these were both technical Halts.
Whatever be it, its a good thing.
Now...
more...

this will be my "Go To Train" for travelling to Delhi.
Doesn't matter how much it delays, but itna toh bharosa hai ki shaam hone se pehle Delhi pahuncha degi..;)
Jokes apart, a Serious question to ask.
I am planning to go Balasore to Amritsar in month of March (specifically March 29th departure). Thinking of 12281 for BLS to NDLS and then some other train for NDLS to ASR.
Kindly suggest me how much buffer should i keep at Delhi for a change over , considering the summers ?
