although the 185s have a lower top speed of 100 miles per hour (160.9 km/h).

The Class 185 trains are designed to be quick accelerators and faster at climbing hills; First TransPennine Express expect these trains to be able to make up time more easily than the 158s should they be delayed due to the higher acceleration afforded by the 2250 hp provided by a 185's engines (as compared with a Class 158

 (RA 5 compared to the RA 2 of a Class 158) which means they are too heavy to run at the faster speed limits designed for sprinter class trains that are in place on some parts of the First TransPennine Express network. Therefore they can only run at the lower standard speed limits. Due to the higher acceleration of the Class 185 they are still able to run to the Class 158 timings on these routes.

s upon arrival in the United Kingdom. Later arrivals were delivered blank and given vinyls at Ardwick Depot, Manchester.

Eco-Mode

Class 185 units can be operated in 'Eco-Mode', which allows one or more of the units' engines to be shut down when not needed to save fuel, without affecting journey times or passenger comfort.

Each of the three carriages in the unit has an engine and all three are used when accelerating out of stations. However, when travelling downhill or running at line speed, only two are needed. Additionally, the train uses only one engine in empty stock moves to depots, and automatically turns off all idling engines when the train is stationary. The result is that the units require 7% less fuel. For the entire fleet of 51 units, carbon emissions are reduced by 12 tonnes (11.8 LT) each day; over 12 months, 1800000 litres (395,944.6 imp gal) of fuel is saved. Furthermore, as the engines are idling less and thus operating less (engine hours reduced by two hours a day per train), their service life

 may be extended by 15%.

Passenger comfort

The general ambience of the trains is rather more commuter-like than the 158s, with wide double doors at 1/3 and 2/3 of the way down the carriages, rather than the usual long-distance train narrow doors at the carriage ends. There is increased standing room, and around half of all seats are arranged around tables of four.

The loss of seats relative to an equivalent three-coach 158 means that more passengers have to stand at peak times. An increase in passenger numbers since the trains were brought in to operation has meant that some passengers are unable to board 185s at peak times due to them being seriously overcrowded.

 on board these trains has, in the past, attracted many complaints from passengers as it was set too cold. A software modification has now been completed and the temperature is somewhat improved: complaints from passengers regarding the temperature have decreased. In the recent cold weather this was a much more serious problem.

Like on 175s, the amount of leg room is good because the backs of the seats are thinner and firmer than on trains such as the 158 and the 170. Additionally there are dedicated wheelchair areas and disabled toilets, additional capacity for bicycles as well as on board CCTV and emergency call points.

The new trains have proved popular with commuters who regularly use the 185s on short journeys. However, they have proved unpopular with long distance travellers who find the standard class seating too firm to sit on for up to four hours, and find the engines to be noisy.

There are reclining seats in First Class, in 2+1 layout, an improvement on the 2+2 layout on the Transpennine Class 158s which they replaced.

Operations

Almost all First Transpennine Express Services are operated by 185s, except for the Manchester Piccadilly – Hull service which are mostly run by a Class 170 Turbostar train. This is due to the speed and weight problems between Selby

. Class 170's also operate a few of the services between Manchester Airport and Cleethorpes via Doncaster and on some Sunday only services between Manchester and York but this has met with criticism as this has resulted in further overcrowding on an already congested route.

However, the 185s are seen as too small for TransPennine Express services, and it is likely eight-carriage units will be needed by 2014 which will need to have a top speed of at least 100 mph (160.9 km/h) to meet targets for reducing journey times.
