A stairway system 10 for a vehicle includes a stairway 12 pivotably retractable about a pivot axis of a main pivot arrangement 46 by a retraction mechanism including an actuator 40. The stairway has treads 14a... 14n each connected to a support structure 18 by a pivot arrangement 16. A tread levelling mechanism 49 maintains an upper surface of the respective tread level during at least part of a stairway retraction phase. The tread levelling mechanism can include a tread levelling control arm connected to each tread and to a control link 60 at the top tread. The link 60 supports a guide roller 56 which contacts a control guide 58 during retraction or deployment to control tread levelling. A distal end of the stairway has a foot or skid 28. 14f 14e 14d 48 14c 14b 44e 14a 38 18Fig 1 36,38 14f 14b4 14c 28 54 Fig2
