Arriva UK Trains stated its aim for a "step-change in quality" for the new trains when compared with older trains in the
Northern fleet such as the
Pacers and
Sprinters. The interior, layout and driver cab of the Class 195 (DMU) are similar to their sister units, the Class 331 (EMU), the differences being in power generation and drivetrain. The 195s have a 'doors-at-thirds' arrangement, and a top speed limited to . They have
air conditioning, power sockets, one toilet per train, open gangways between individual carriages, passenger compartment
CCTV, provision for wheelchair passengers, and a
Wi-Fi system. All trains are fitted with an automated audio information system, as well as display screens - six in each carriage, ensuring all passengers have an unobstructed view of at least one. These screens convey a variety of information, including station arrival times and informing alighting passengers when they need to be in a different carriage due to platforms being too short to accommodate the train. Northern selected a "wide and spacious" vestibule area to allow for quicker passenger flows when boarding and disembarking to minimise dwell times and thus reduce delays. The large spaces around the doors create a flexible space, with flip-down seats for quiet times of day, and standing space in times of overcrowding where the objective is to ensure that all passengers can board. Since the units are not fitted with fixed luggage racks (as these often reduce capacity on peak-time commuter trains) the space by the doors can also be used to store luggage and prams - thus not impacting on the capacity of the train or safety of passengers wishing to alight or board. In maintaining an objective for the interior to be spacious, seats are cantilevered off the body frame and there are no internal doors, with open gangways between carriages. The units were designed with a projected lifespan of 35years and it was planned they will operate beyond 2050 with maintenance and refurbishment. A feature is a digital seat reservation system, however this is to future-proof the train and Northern did not envisage using it on many, if any routes. Although the vast majority of services operate as three- or four-car formations (two-car units doubled), some three-car units will be doubled up to form six-car services, such as the route between Manchester Oxford Road and Liverpool via Warrington Central. As a result, they are fitted with
Automatic Selective Door Operation (ASDO) for use on routes where station platform lengths are not sufficient to fully accommodate the train. This ASDO system is linked to an automated system which informs the passengers through both audio announcements and the passenger information screens in each saloon. ==Operators==
