How to use rail fishplate to fix the steel rail?

Rail fishplates, also known as rail joint bars or splice bars, are used to connect two steel rails end to end to create a continuous track. They are an essential component of railway infrastructure, ensuring safe and smooth operations. In this article, we will explain how to use rail fishplates to fix steel rails.

Step 1: Gather the necessary tools and equipment

Before you start fixing the steel rails with rail fishplates, it is essential to gather all the necessary tools and equipment. The tools you need may include a wrench, a hammer, a drill, and bolts. The equipment required may include rail fishplates, rail spikes, and rail anchors.

Step 2: Align the rails

The first step in fixing the steel rails with rail fishplates is to align the rails. The rails should be aligned correctly, and the gap between the two rails should be consistent throughout. Any deviations or irregularities in the alignment could lead to track failures or derailments.

Step 3: Clean the rails

Once the rails are aligned, it is essential to clean the rail ends thoroughly. The rail ends should be free from any dirt, rust, or debris that may interfere with the installation of the rail fishplates. You can use a wire brush or a grinder to clean the rail ends.

Step 4: Position the rail fishplates

The next step is to position the rail fishplates on either side of the rail ends. The rail fishplates should be placed in such a way that they cover the joint between the two rails entirely. Make sure that the bolt holes in the rail fishplates align with the bolt holes in the rails.

Step 5: Insert the bolts

Once the rail fishplates are positioned correctly, you can insert the bolts through the bolt holes in the rail fishplates and the rails. Tighten the bolts using a wrench or a spanner. Make sure that the bolts are tightened evenly to prevent any stress concentration on the rail fishplates.

Step 6: Install rail spikes

After the bolts are tightened, you can install rail spikes to secure the rails to the sleepers or ties. The rail spikes should be driven into the holes provided in the rail base. The spikes should be hammered in such a way that they secure the rails firmly to the sleepers.

Step 7: Install rail anchors

Finally, you can install rail anchors to prevent the rails from shifting or moving. The rail anchors should be positioned at a distance of about 24 to 30 inches from the joint. The rail anchors should be hammered into the ballast bed using a rail anchor hammer.

In conclusion, fixing steel rails with rail fishplates requires careful planning and execution. It is essential to align the rails correctly, clean the rail ends thoroughly, position the rail fishplates accurately, insert the bolts evenly, install rail spikes securely, and install rail anchors to prevent the rails from shifting. By following these steps, you can ensure safe and smooth railway operations.
