Additional to a trolley service there is a "Café Bar" serving alcohol, soft drinks, tea & coffee and hot and cold snacks. The seating in the Cafe Bar is the same as the other rail seats, with the same tables. First Plus comes with more leg room, reclining seats, tinted windows with blinds, complimentary newspapers (on most services the two main Belfast papers but on occasion the Irish Independent and Irish Times are available). Food is available for purchase in First Plus with a full three-course menu serving breakfast (before 12pm), lunch and dinner (after 12pm). Tea and Coffee from this menu come with complementary refills. First Plus is also significantly quieter as it is rare for either First Plus carriage to be full to capacity. A member of the train crew checks passengers tickets at the door to the First Plus carriages, since many people are unaware there are two classes of carriage on the train. Both classes have air conditioning vents designed into the rim of the window frames and free WiFi supplied by NI Railways. The WiFi is limited to 150MB of data each day per device. A glass display is atop the door of every carriage showing an analogue clock face with the current time, the destination station, the next station, and any other information may be scrolled down the bottom of the display. Approximately 3 minutes from every stop the computer will announce "we are now approaching (station name)" to give passengers enough time to gather their belongings before disembarking. Since the Enterprise brand aims to be politically neutral, there are no Irish Rail or NI Railways logos inside or outside the train (with the exception of the alcohol consumption policy poster, which includes the logos of both operators), only Enterprise specific branding, all announcements are made only
