What is a rail shoulder?
Rail shoulder is cast in the concrete rail ties to fix the elastic rail clips. There are two types of rail shoulders available, the cast-in shoulder and the weld-on rail shoulder, both of which are used for the fixing of elastic rail clips.
Cast-in Rail Shoulder.
The casting shoulders as the embedded part of the rail way fastening system are pressed in concrete sleeper and work together with the E clip to fasten the rail. The cast in shoulder is made by casting from iron, such as, GB/T 1348-1988, NF EN 1563(1997), ISO1038, DIN 1693, JIS G5502 (2001), KS D 4302, GOST 7293(1985) or BS EN 1563(1997).
Weld-on Rail Shoulder
The weld-on shoulder is used at the typical position of rail where the rail shoulder is weld on flat steel plate rather than the standard tie plate. The weld-on shoulder production method is hot forging, it is fabricated according to AREA standard. The steel material type for weld-on shoulders production can be low or medium carbon steel, which varies with your specific requirements.
Features of railway shoulders
Designed for use with E style elastic rail clips, the weld on shoulder fastening allows customers to fabricate rail retaining units on both steel sleepers and steel base plates.
The rail cast iron shoulders can also be welded on to longer length steel sleeper sections or bearers for use in the fabrication of switch and crossing layouts where vertical rail geometry is employed. The railway shoulder’s ability to be welded in the specific position as dictated by the layout design makes it particularly useful and cost effective in this role.
Installation attention of Rail Shoulder:
When assembling, you should first determine the direction that needs to prevent the rail from crawling, and place the wooden bearing plate, and clamp the main and auxiliary bodies of the rail anchor on the bottom edge of the rail, so that the active surface of the rail shoulder is consistent with the crawling direction of the rail, and then follow the rail Insert the connecting bolt at one end of the anchor body, add a flat washer and a spring ring, and screw the nut so that the active surface of the rail anchor is in close contact with the wooden bearing plate, and finally tighten the bolt with a torque of 150 N m. Tighten the connecting bolts after 2 to 3 weeks of use. It should be noted that it is strictly forbidden to hit the installed rail anchor with a heavy hammer to prevent damage to the rail anchor under high stress.
Notes on rail shoulders
The weld-on shoulder fastening makes it possible to manufacture the rails retaining units on the steel sleeper and the steel base plate when the E-shaped rail clamp is used for rail fastening.
Even if the cast-in shoulders are usually embedded in the concrete rail sleeper, they can be welded to a longer length of the steel track section or bearers for the manufacture of switches and cross arrangements using vertical rail geometries.
The welding capacity of the rail shoulders is determined by the layout design, which makes the railroad shoulder more useful and cost-effective.
The rail shoulder accessories for a particular rail section shall be used in accordance with the design criteria to achieve proper elastic chuck toe loading. And certain rail shoulder with a milling area need to be provides to achieve better weld integrity.
The Functions of Rail Shoulder
Load Distribution:
Rail shoulders help distribute the vertical loads from the rails and passing trains evenly onto the sleepers. This prevents excessive stress on individual sleepers and the underlying trackbed, enhancing the overall stability of the track.
Cushioning and Protection:
Rail shoulders serve as a cushion between the rail and the sleeper, reducing direct contact and preventing damage due to impact and vibration. This can extend the lifespan of both the rail and the sleeper.
Vibration Damping:
The use of rail shoulders can help dampen vibrations generated by passing trains, leading to reduced noise levels and a more comfortable environment for nearby residents.
Rail Alignment:
Rail shoulders also play a role in maintaining proper rail alignment, ensuring that the rails stay in position and maintain the correct gauge (distance between the rails).
Installation:
Rail shoulders are designed to be easily installed on the sleepers. They are typically secured using fasteners like bolts or clips, and their design allows for proper positioning and alignment with the rail base.
The Difference Between Cast-in Rail Shoulder and Weld-on Shoulder
Installation method
The cast-in shoulder is integrated into the sleeper during the manufacturing process, and the shoulder is poured directly into the concrete or other materials of the sleeper. Weld-on shoulder is fixed to the rail seat by welding and they are welded directly to the rail foot.
Connection
The cast-in shoulder fits firmly into the sleepers to form a unified structure without the need for additional fasteners or welding. Weld-on shoulder is welded directly to the rail for a strong and permanent connection.
Durability
Cast-in rail shoulder and Weld-on shoulder have good durability due to their integrated features. Rail shoulders and sleepers function as a whole, and the connection between them is usually firm and stable.
Installation techniques
Prefabricated sleepers require a specialized manufacturing process during sleeper production, which may be performed in a prefabrication factory, which reduces the need for on-site welding and installation expertise. Weld-on shoulder requires specialized skills and equipment, proper welding procedures must be followed to ensure a strong and reliable connection, and installation requires welding experts.

FAQ
01.What is the advantages of a weld on Rail Shoulder?
Designed for use with elastic rail clips, the weld on shoulder fastening allows customers to fabricate rail retaining units on both steel sleepers and steel baseplates. Their ability to be welded in the specific position as dictated by the layout design is particularly useful.
02.Why do railway tracks need regular maintenance?
Railway track is loaded with dynamic railway vehicles and always works in the exposed natural environment, which may cause abrasion, deformation, damage of relevant parts, change of geometry size etc. Therefore, with working hours increase, it is necessary to carry out regular maintenance in order to ensure the quality of railway track and the integrity of the equipments.
In general, Maintenance of railway track is to take periodic repairing, mainly including periodic updating, periodic comprehensive maintenance, regular inspection and key repairing of track.
03.What are the common types of damage to railway rail shoulders?
