The British Rail Class 365 "Networker Express" are dual-voltage (25 kV AC and 750 V DC) electric multiple units built by ABB at York, from 1994 to 1995. These were the last units to be built at the York factory before its closure. All Class 365 units in service have received front-end cab modifications to equip them with cab air conditioning, installed by WAGN, the design of which has given them the nickname "Happy Train".
