Current collector (STA) for a rail vehicle which is intended for cross-border transport, - having a support (TR) and having two contact strips (SL1, SL2) which have a first length (L1), - in which the support (TR) is designed in such a way that, on the roof of the rail vehicle, it orients the two contact strips (SL1, SL2) transversely with respect to the direction of travel of the rail vehicle and brings them into electrically conductive contact with a contact wire, - in which each contact strip (SL1, SL2) has a respective contact strip extension (SLV11, SLV12, SLV21, SLV22) at each end (SLE11, SLE12, SLE21, SLE22), - in which the respective contact strip extension (SLV11, SLV12, SLV21, SLV22) is connected to the respective end (SLE11, SLE12, SLE21, SLE22) of the contact strip (SL1, SL2) in a manner mounted rotatably about a vertical axis, - in which, in a first position (POS1), the contact strip extensions (SLV11, SLV12, SLV21, SLV22) are arranged with respect to the contact strip (SL1, SL2) by rotation about the vertical axis in such a way that a resulting total length of the contact strip (SL1, SL2) with the associated contact strip extensions (SLV11, SLV12, SLV21, SLV22) corresponds to the first length (L1) of the contact strip (SL1, SL2), and - in which, in a second position (POS2), the contact strip extensions (SLV11, SLV12, SLV21, SLV22) are arranged with respect to the contact strip (SL1, SL2) by rotation about the vertical axis in such a way that the resulting total length of the contact strip (SL1, SL2) with the associated contact strip extensions (SLV11, SLV12, SLV21, SLV22) corresponds to a second length (L2), which is greater than the first length (L1). - having a support (TR) and having two contact strips (SL1, SL2) which have a first length (L1), - in which the support (TR) is designed in such a way that, on the roof of the rail vehicle, it orients the two contact strips (SL1, SL2) transversely with respect to the direction of travel of the rail vehicle and brings them into electrically conductive contact with a contact wire, - in which each contact strip (SL1, SL2) has a respective contact strip extension (SLV11, SLV12, SLV21, SLV22) at each end (SLE11, SLE12, SLE21, SLE22), - in which the respective contact strip extension (SLV11, SLV12, SLV21, SLV22) is connected to the respective end (SLE11, SLE12, SLE21, SLE22) of the contact strip (SL1, SL2) in a manner mounted rotatably about a vertical axis, - in which, in a first position (POS1), the contact strip extensions (SLV11, SLV12, SLV21, SLV22) are arranged with respect to the contact strip (SL1, SL2) by rotation about the vertical axis in such a way that a resulting total length of the contact strip (SL1, SL2) with the associated contact strip extensions (SLV11, SLV12, SLV21, SLV22) corresponds to the first length (L1) of the contact strip (SL1, SL2), and - in which, in a second position (POS2), the contact strip extensions (SLV11, SLV12, SLV21, SLV22) are arranged with respect to the contact strip (SL1, SL2) by rotation about the vertical axis in such a way that the resulting total length of the contact strip (SL1, SL2) with the associated contact strip extensions (SLV11, SLV12, SLV21, SLV22) corresponds to a second length (L2), which is greater than the first length (L1). <EOS>
