How to reach Hajipur?

Hi people of Patna, I will land the airport in evening and I have a train to catch from Hajipur to Chhapra. I need to reach Hajipur railway station. What is the best route? So far, I have found that I can go to ISBT Bairiya from Patna airport and then take bus to Hajipur bus stand (Ramashish Chowk Golamber). Is there a better route?
