Aluminium alloy vehicles have been carefully designed to attain the optimum eight of buffer attachments. Buffer attachments are located in holes 6.5mm diameter ad clamped by screw at each end of the vehicle. A vertical 4mm diameter hole in the center of each vehicle enables the white plastics rod to be used to indicate the positions of vehicles on stroboscope photographs. Vertical slots in the top of the vehicles enable white cards to be positioned for photoelectric timing applications. The vehicles buffer attachment and clamping screw are finished in matt black to the interpretation stroboscopic photographs
