I have to book four 3AC tickets in this train to Jammutawi for date 15.03.18. 2 persons will board this train at Durgapur and 2 others at Parasnath. Suppose I book for all four from "Durgapur to Jammutawi" in one go- will this create any trouble as 2 of them will board later at Parasnath? Will telling TTE regarding the same suffice?
