Each diaphragm assembly (10) includes a mounting plate (15) having vertical sections (17, 18) at the side of door (11) and an arch portion (19) above door (11) mounted to a car (12). The mounting plate (15) is of a predetermined lateral width and carries side portions (22) of a flexible membrane (21). A bridge portion (23) of flexible membrane (21) extends between side portions (22) and is attached to a face plate (25) which has vertical sections (26, 27) at the side of door (11) and an arch portion (28) above door (11). The face plate (25) has a predetermined lateral width greater than the width of mounting plate (15). Face plates (25) of adjacent cars ( 12) are adjacent to each other and a seal assembly (40) may be provided between the arch portions (28) thereof to prevent liquid from entering the passageway. At the bottom of the diaphragm assembly (10), a sill membrane (70) is attached to a sill plate (29) which is mounted between the vertical sections (26, 27) of the face plate (25). …
