So you are trying to say is that this is the revenge that they want to take by extending a highly popular train that runs full throughout the year?? Moreover, even if I consider your statement, then what is the fault of the Asansol-Raniganj-Durgapur belt passengers because if this extension happens (which is very unlikely to happen), then they will be affected the most. Afterall, the normal citizens as a whole had never protested to provide any train service to the aforesaid sections.
Btw, as far as my knowledge goes, Giridih had a direct link train to Kolkata till 2020. It was in 2020 when this connection was discontinued.
