A bogie (10, 110) for a railway vehicle comprising: - a bogie frame (12, 112); - at least one pair of wheels (18, 118) rotatable relative to the frame (12, 112), and - at least one secondary suspension (22, 122) configured to connect the bogie (10, 110) to a vehicle body, the frame (12, 112) comprising at least one first longitudinal member (30A, 130A) extending substantially in a longitudinal direction, at least one second longitudinal member (30B, 130B) extending substantially parallel to the first longitudinal member (30A, 130A), at least one first cross-member (42A, 142A) and at least one second cross-member (42B, 142B) each extending in a transverse direction substantially perpendicular to the longitudinal direction, the first and second cross-members (42A, 42B, 142A, 142B) respectively connecting the first and second longitudinal members (30A, 30B, 130A, 130B) to one another, characterised in that the height of at least part of the secondary suspension (22, 122) is less than a minimum height of the chassis (12, 112) in a direction of elevation substantially perpendicular to the longitudinal direction and to the transverse direction, the heights being measured with respect to the rails on which the bogie is intended to travel. - a bogie frame (12, 112); - at least one pair of wheels (18, 118) rotatable relative to the frame (12, 112), and - at least one secondary suspension (22, 122) configured to connect the bogie (10, 110) to a vehicle body, the frame (12, 112) comprising at least one first longitudinal member (30A, 130A) extending substantially in a longitudinal direction, at least one second longitudinal member (30B, 130B) extending substantially parallel to the first longitudinal member (30A, 130A), at least one first cross-member (42A, 142A) and at least one second cross-member (42B, 142B) each extending in a transverse direction substantially perpendicular to the longitudinal direction, the first and second cross-members (42A, 42B, 142A, 142B) respectively connecting the first and second longitudinal members (30A, 30B, 130A, 130B) to one another, characterised in that the height of at least part of the secondary suspension (22, 122) is less than a minimum height of the chassis (12, 112) in a direction of elevation substantially perpendicular to the longitudinal direction and to the transverse direction, the heights being measured with respect to the rails on which the bogie is intended to travel. the frame (12, 112) comprising at least one first longitudinal member (30A, 130A) extending substantially in a longitudinal direction, at least one second longitudinal member (30B, 130B) extending substantially parallel to the first longitudinal member (30A, 130A), at least one first cross-member (42A, 142A) and at least one second cross-member (42B, 142B) each extending in a transverse direction substantially perpendicular to the longitudinal direction, the first and second cross-members (42A, 42B, 142A, 142B) respectively connecting the first and second longitudinal members (30A, 30B, 130A, 130B) to one another, characterised in that the height of at least part of the secondary suspension (22, 122) is less than a minimum height of the chassis (12, 112) in a direction of elevation substantially perpendicular to the longitudinal direction and to the transverse direction, the heights being measured with respect to the rails on which the bogie is intended to travel.
