The rail line orbit must use different types of profiled rail connection
Shaped joints are divided into two kinds: one is the use of special-shaped plywood between different types of rail, which is extremely easy to damage; the other is the use of special-shaped rail, that is, a rail is divided into two parts.
Shaped rail refers to a complete rail, one end is a rail type, and the other end is another rail type, is obtained by forging process.
When different types of rail connection section need, because the rail section size is different, need a fishtail splint or rail to rail, or called fish shaped tail splint splint or the connection of different section type profiled rail rail.
Rail section size adopted by railway track is different. Our country now uses four types of 75kg/m, 60kg/m, 50kg/m, 43kg/m and two types of 45kg/m and 38kg/m that have been eliminated.
The sizes of different types of rails are different. To ensure the reliable connection between the two types of rails and the top of rail, the special-shaped joints must be used.
