Heart with wing rail vertical speed rail transition turnout basics on track direction, due to the use of special low-profile cross-section tip rail, eliminating the common rail tip 6mm vertical rail that irregularity than the basic track elevation in part in frog matches are more "75" type of turnout is more reasonable to ensure the longitudinal stability during high-speed driving. Using special low-profile cross-section of the rail track speed Turnout conservation tips, including 60kg / m and 75kg / rn rail turnouts use 6OAT rail, 50kg / m rail turnout 50AT rail use. Improve the strength and reliability of the guard rail. There Groove guard rail and H type two. Groove guard rail which uses channel No. U1C33 speed turnouts manufacturing fault analysis, H-type guard rail with a low-level rail manufacturing (eg 60kg / m of frog guard rail with 50kg / m rail manufacturing). For t improve safety guard rail at high speed lane, guard rail of the top rail of the top higher than the basic 12mm. Turnout fastener strength than the "75" model has improved greatly. For example the use of wedge adjustable rail brace, rigid split-arc plate buckle fasteners, threaded portion of the guide curve spike, spike, and so cancel hook.
