The British Rail Class 365 Networker Express were dual-voltage (25 kV AC and 750 V DC) electric multiple-unit passenger trains built by ABB at Holgate Road Carriage Works in 1994 and 1995 to operate services in South East England and on the Great Northern Route. These were the last trains to be built at the Holgate Road works before its closure. Due to the refurbished front end resembling a smiling face, the trains were nicknamed "Happy Trains" by enthusiasts.
