What is the difference between the rail lead line and the rail connection line?
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.
The 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 rail line orbit must use different types of profiled rail connection:1, different types of rail size is not the same, to ensure that the two types of rail between the reliable connection, and rail top surface and so on, we must use special-shaped joints.2, special-shaped joints are divided into two kinds: one is between different types of rail using special-shaped plywood, this way is extremely easy to damage; the other is the use of special-shaped rail, that is, a rail is divided into two parts.
