The invention relates to an underfloor wheelset inspection device (1) for inspecting a first wheelset (2) and a second wheelset (3) of a railway vehicle, each wheelset (2, 3) comprising a right wheel (21, 31) and a left wheel (22, 32) connected by an axle (23, 33). The underfloor wheelset inspection device (1) comprises: a control unit (4), a first wheelset inspection unit (5) for the first wheelset (2) and a second wheelset inspection (6) unit for the second wheelset (3), each of the wheelset inspection units (5, 6) comprising: a first wheel lifting unit (51, 61) configured to lift and rotate the left wheel (22, 32) of the corresponding wheelset (2, 3); a second wheel lifting unit (52, 62) configured to lift and rotate the right wheel (21, 31) of the corresponding wheelset (2, 3). The underfloor wheelset inspection device (1) further comprises a probe unit (53, 63) comprising a sensor (531, 631) and a movement device (532, 632) for moving the sensor (531, 631) between a left sensing position in proximity to a running tread of the left wheel (221, 321) when lifted by the first wheel lifting unit (51, 61) for probing the running tread of the left wheel (221, 321) and a right sensing position in proximity to a running tread of the right wheel (211, 311) when lifted by the second wheel lifting unit (52, 62) for probing the running tread of the right wheel (211, 311). The control unit (4) is operatively connected to the first wheelset inspection unit (5) and to the second wheelset inspection (6) unit and wherein the control unit (4) is suitable and set up to operate both probe units (53, 63) simultaneously to perform a probing of the running tread of a wheel (211, 311, 221, 321). The probe unit (53, 63) further comprises an environment sensor unit (533, 633) with a proximity sensor and/or a force sensor.
