Abstract: Offset racing rail arrangements (16) of the fixed and relocatable variety are made safer by fitment of a cover designed to prevent riders from falling between and sometimes onto the poles which support the racing rail. A cover (22) is provided which is releasably attachable to a receptacle portion of the rail which is also resiliently spaced by a support means from the posts (10) which support the rail. The cover (22) is one embodiment comprises sheet material (24) bent (30, 32, 34, 36 and 38) underneath itself in such a manner as to provide a resilient self supporting spacing from each posts (10). The cover (22) is also in the embodiment provided with an edge portion (26) adapted to releasbly attach to a receptacle portion (56) of the rail without the use of fasteners.

Abstract: The movement of relocatable racing rails (10) by manual labor involves the extraction of poles (16) from the ground and re-insertion of each pole a fixed distance from its adjacent pole along the path of the new location of the racing rail, thereby resulting in a time consuming and very labor intensive operation wherein inaccuracies in placement of the poles can result in misfits of the relocatable rails over the poles, whereby readjustment is often required. A transportation apparatus (28) is provided for carrying poles (16) and measuring a fixed distance between the last pole and a pole driver mechanism (32) for driving the next pole (66) into the ground. The pole driver is allowed to move relative to the transportation apparatus as the apparatus moves along the ground, but the relative movement is arranged so as to maintain a fixed distance to the last pole for a time shortly before, during and after the pole driver mechanism is actuated to drive a pole into the ground.
