Class 166 Networker Turbo Express

The Class 166 "Networker Turbo Express" was built alongside its DMU sister class the Class 165 for longer distance routes between London Paddington, Oxford and Newbury. The Class 166 is very similar to the 165 but has a more luxurious interior including first class seating, two toilets, carpeted flooring, air conditioning and more luggage space [1]. They are capable of one hundred and forty five kp/h unlike some 165s which are limited to one hundred and twenty kp/h.
