Why ?? Hisar, Bhiwani and Rohtak won't want seats after extension ? If the coach composition is staying the same and the train is being extended from Delhi to Rohtak, then Bhiwani, then Hisar and now it's being demanded to extend Sirsa. Don't you think these extensions would affect the number of seats available for people from Delhi ??
Same for other extensions too.
Look I'm not targeting Hisar here, Hisar deserves trains for its own and I'm really happy that it's getting the same. I just simply don't support extension of already...
more... successful trains of their respective routes for same. Now if Shramshakti Express, Shiv Ganga Express, Prayagraj Express, Lucknow Mail, Purushottam Express like trains are extended the same way then it'd surely affect the passengers to/from Delhi and we simply can't tolerate that. If they want to use the rake further then they could introduce another separate service with the help of RSA.
Regarding cleanliness obviously a train starting from Delhi would be much cleaner (for Delhi based passengers) than a train coming to Delhi and then continuing it's journey.
Hope you take it in positive way.
