Railway vehicle, comprising at least one shell and at least one bogie carrying the shell, the one or each bogie comprising: - a chassis; - two pairs of wheels connected by an axle, each axle being mounted mobile in rotation on a pair of axle boxes; - a primary suspension system associated with each axle box and disposed between the chassis and said axle box; - at least two secondary suspension systems, each disposed between the chassis and the shell, including a first secondary suspension system and a second secondary suspension system; - a first regulating member associated with said first secondary suspension system and able to modify the restoring force of said first secondary suspension system as a function of the spacing to the shell from a first reference point; - a second regulating member associated with said second secondary suspension system and able to modify the restoring force of said second secondary suspension system as a function of the spacing to the shell from a second reference point; - a first control system of the first regulating member which is able to have an influence on the position of the first reference point relative to the shell as a function of the arrow of the first secondary suspension system and of the arrow of a respective primary suspension system formed by a first primary suspension system; - a second control system of the second regulating member which is able to have an influence on the position of the second reference point relative to the shell as a function of the arrow of the second secondary suspension system and of the arrow of a respective primary suspension system formed by a second primary suspension system; each control system comprising: - a measuring member which is able to measure the arrow of the respective primary suspension system; - an actuator which is fixed to the chassis and able to adjust the spacing from the reference point to the chassis, said actuator being controlled by the measuring member so that the spacing from the reference point to the chassis is a function of the arrow of said respective primary suspension system; and - a teleforce cable which is able to make the actuator be controlled by the measuring member. - a chassis; - two pairs of wheels connected by an axle, each axle being mounted mobile in rotation on a pair of axle boxes; - a primary suspension system associated with each axle box and disposed between the chassis and said axle box; - at least two secondary suspension systems, each disposed between the chassis and the shell, including a first secondary suspension system and a second secondary suspension system; - a first regulating member associated with said first secondary suspension system and able to modify the restoring force of said first secondary suspension system as a function of the spacing to the shell from a first reference point; - a second regulating member associated with said second secondary suspension system and able to modify the restoring force of said second secondary suspension system as a function of the spacing to the shell from a second reference point; - a first control system of the first regulating member which is able to have an influence on the position of the first reference point relative to the shell as a function of the arrow of the first secondary suspension system and of the arrow of a respective primary suspension system formed by a first primary suspension system; - a second control system of the second regulating member which is able to have an influence on the position of the second reference point relative to the shell as a function of the arrow of the second secondary suspension system and of the arrow of a respective primary suspension system formed by a second primary suspension system; - a measuring member which is able to measure the arrow of the respective primary suspension system; - an actuator which is fixed to the chassis and able to adjust the spacing from the reference point to the chassis, said actuator being controlled by the measuring member so that the spacing from the reference point to the chassis is a function of the arrow of said respective primary suspension system; and - a teleforce cable which is able to make the actuator be controlled by the measuring member.
