I ordered these safety rails as the flexible barriers supplied with the Carrera Digital 143 circuit are really not strong and the traffic was all the time around when turning, especially in the learning phase when not yet mastered very good speed. While these soft plastic rails are perfect: even in case of slippage cars remain on the track, no need to pick them up at the other end of the room! The only regret: the track should be part of the circuit and not sold separately!
