The decision about the gangways was decided in January 1924 with Pullman Gangways being adopted. The bridge originally had thick stone balustrades, with very narrow pedestrian gangways beside them. Some passengers were able to reach the water via the gangways and rope ladders. Accessible vehicles also have wider entrances and interior gangways and space for wheelchairs. It involved replacing the existing retractable gangways and couplers between coaches. All three crossbars are equipped with gangways that carry additional smaller antennas. The floors are connected by gangways and stairs. This is usually at end uprights located at the intersections of aisles and gangways. The units are fitted with large round oleo buffers, and have no gangways between carriages. They use Jacobs bogie, which allow for thin and wide gangways between each coach. It has jacobs bogies shared between the individual coaches, with wide walk-through gangways. The assault troops gathered by platoon at their assigned gangways and clambered into the LCAs. It has double leaf sliding doors, gangways, CCTV cameras and aluminium luggage racks. The aisles and walk-through gangways are also wider when compared with the previous fleet.
