Rail Tie Plate

Rail tie plate is also called rail base plate or sole plate, it is a main component in railroad construction of a crane rail or track support system.

Functions of rail tie plates

Rail tie plates are used not only to support the rails, but also to fix the entire rail fastening systems. It always works together with anchor bolts or spikes by sustaining the load of a rail track and also transferring part of the load to the tie sleepers, with a flat smooth resting surface to guarantee the vertical alignment and hold the rail in correct gauge for a rail line system.

All in all, rail tie plates are used to given a smooth and uniform bearing surface for the rail and the tie in order to prevents the rail from cutting into the tie, maintain gauge, and also helps to better distribute the wheel load to ties.

Agico Rail is capable of producing rail tie plates by either casting(welded or fabricated type) or forging or rolling, applicable of different rail sections, for wooden, steel or concrete sleepers, depending on the load and rail standard, i.e. UIC 60, UIC 54, RN 45, 90 A, etc.

Types of rail tie plates:

Rail tie plates can be classified depending on either a single or double shoulder construction, to supply various ribbed tie plates.

1. Single shoulder tie plates

For the tie plates of single shoulder, the shoulder is designed at the field end of the plate. The plate’s short end or gauge end is placed inside of the rail track, and that why the rail base width is always required from clients. Single shoulder tie plates are usually used by rails weights running from 56lb though 100 lb.

2. Double shoulder base plates

For a sole plate of double shoulder, types of 2-hole, 4-hole, 5-hole, 6-holes or 8-hole are all available according to customer requests. Double shoulder plates are usually used for rail that is larger than 100 lb.

3. Casting rail tie plate

Casting is a common technology to produce rail tie plates, which is also a cost saving way.

• Name: casting rail tie plate
• Type: Applicable of rail UIC54, UIC60, 50kg rail, 60kg rail,S49 and size as ordered
• Material: QT500-7 or QT450-10 (low carbon steel or high carbon steel by forging, and low carbon steel S275JR, Q235,etc. by rolling.)
• Standard refers: UIC864-6

4. Base plates for KPO fastening systems

A rail base plate is a key part in KPO fastening system to support the rail and fix the whole fastening systems, tied onto the rail with rail bolts and railroad spikes.

5.AREMA standard tie plate

For American market, the common sizes include 11inches, 14inchies and 14-3/4inches tie plate, they are generally for 5-1/2inches and 6inches width rail base.

6.AREMA hook twin tie plate

HTTP, whose full name is hook twin tie plate, is widely used for turnouts positioned behind the switch bottoms. In order to ensure the tie spacing, the HTTP is often used in pairs to a single tie. Among the products, the 1st AREMA hook twin tie plate producer of both 3/4’’ and 1’’ thick in China.
Different available varieties:
