• at least one rear guide wheel located at the back end of the frame, wherein the front guide wheels and the at least one rear guide wheel are configured to engage the rails of the railway line;
• and
• two transport wheels, each said transport wheel being pivotably attached on opposing sides of the wheel frame via a respective wheel swing arm;
• and
• a buffer subunit comprising:
• a buffer frame pivotably attached to the wheel frame;
• two circular buffer heads, each of said buffer heads being located at opposing sides of the buffer frame between the front guide wheels and the at least one rear guide wheel, wherein the buffer heads are configured to contact the rails;
• and a motor located on the buffer frame, wherein the motor is configured to drive the rotation of the buffer heads to buffer the rails;
• wherein the buffer frame is configured to pivot between a first disengaged position and a second buffing position.
