Beginning 01 July 2014, if you will be travelling on Trains G1234 or G1235, which is in fact one service from Changchun to Shanghai Hongqiao, please be prepared for a “full interchange” at Tianjin West Railway Station.
All passengers from Changchun who are heading to destinations beyond Tianjin West in the direction of Shanghai Hongqiao must transfer to a separate train at Tianjin West station. However, you will still be seated in the same carriage and seat number, even in the new train.
Please prepare all bags and personal belongings as the train arrives at Tianjin West. Follow rail staff instructions to transfer to your connection to Shanghai.
