Yes. It was on the day of Champaran HS inaugural run. I saw GKP pictures of my dad and it was not electrified then. My train reached BT at GKP. I got off to buy some biscuits and cake. It was somewhat 3 in the morning. I saw the station was a complete change than what I saw in dad's picture. Electrified station, Longest PF. Shops open at midnight. People were waiting for trains and it was quite cold in April. Just liked the environment there.
