The British Rail Class 166 ''Turbo Express'' is a fleet of diesel multiple units (DMUs), originally specified by and built for British Rail, the then United Kingdom state owned railway operator. They were built by ABB at York Works between 1992 and 1993. The trains were designed as a faster, air conditioned variant of the Class 165 ''Turbo'', intended for longer distance services, and, like the 165s, belong to the Networker family of trains. They were originally known as ''Networker Turbos'' to distinguish them from the electrically propelled members of that family. The class is still in service, and is extensively operated by Great Western Railway on its services out of London Paddington station. The trains, along with that operator's Class 165 trains, are often known as ''Thames Turbos''. ==Description== These units are a modification of the Class 165 design. They have a top speed of (suitable for mainline use), are carpeted throughout and have air-conditioning. Externally, the class 166 can be distinguished from a Class 165 by opening hoppers on every other window. Until late 2013 the presence of first class at each end was another distinguishing feature Other differences over a 165 are as follows: *Air conditioning *Two toilets (a 165 only has one toilet per unit) *Tables in first class and in one third of the middle carriage *Dedicated cycle/luggage storage in the middle carriage *Different interior panelling between the door and seating areas Twenty-one 3-car units were built, numbered 166201-221. Each unit was formed of two outer driving motors, and an intermediate motor. The technical description of the formation is DMSL+MS+DMCL. Individual carriages are numbered as follows: *58101-58121 - DMSL changed from DMCO in 2013 *58601-58621 - MSO *58122-58142 - DMCO The units were built to replace elderly Class 117, Class 119 and Class 121 DMUs, and locomotive-hauled trains on services from London Paddington along the Great Western Main Line. Six cars were added to the original order in 1991 after Network SouthEast acquired some of the Cotswold Line services from Regional Railways to allow Class 158 units to be converted to Class 159s for the ''West of England'' services.〔(【引用サイトリンク】 title=Class 159 )〕 Class 166 units were some of the first trains in Britain to be designed for Driver Only Operation, in cases where a Guard is required they must carry out their door operation duties via a bell system to signal the Drivers to close doors and start the train. This requires the Guard to return to a vacant cab at each station to carry out these duties, examples of this Great Western Railway services on the Cotswold Line. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「British Rail Class 166」の詳細全文を読む スポンサード リンク
