A main undercarriage train for an aircraft which is retractable substantially laterally, the train comprising two undercarriages which comprise identical legs each having a plane of symmetry which passes through its pivot mounting axis which is inclined relative to the plane of symmetry of the aircraft. Each undercarriage further comprises a bush capable of being retained in either of two positions in a bore of the undercarriage leg or a wheel-carrying member and the internal bore of which, through which internal bore passes a shaft on which an assembly for alignment of the wheels are pivoted, has its axis off-set with respect to the axis of the bore in which the bush is retained, and compensates for the angular displacement between the plane of symmetry of the aircraft and the inclined axis of the one or the other undercarriage leg, depending on whether the bush is retained in a first of the two positions or in a second of the two positions which is obtained from the first of the two positions by rotating the bush through 180 DEG about the axis of its bore, whereby the left and right undercarriages are totally interchangeable.
