The railroad has been one of the most reliable ways for transportation of both people and goods. Since the first ever railroad was constructed back in the 1800’s, many like it is seen and used all over the world to this very day. While many have used rails for their daily commute, most people don’t bother to look down to see the different parts of the rails.
For railroad enthusiasts, or those who just want to know more about rail nuts, fastener, and the different parts, here are the basics:
Rail Spikes
A rail spike is also called the crampon or the cut spike and resembles that of a large nail with an offset head. It is used to secure the rails and the base plates to the sleepers or the railroad ties which are located on the tracks.
Screw Spikes
Although called spikes, the screw spikes are actually very large bolts that are used to fix the tie plate properly and securely on the rail. These are commonly installed inside a hole that is drilled within the sleeper itself. They are more expensive than the traditional rail spikes, but are more stable and have a much greater fixing power.
Spring Spikes
These are also known as elastic rail spikes and are commonly used with the flat-bottomed rails, baseplate, as well as wooden sleepers. This spike holds down the rail to prevent slipping while at the same time securing the baseplate and the sleeper.
Fang Bolt
These bolts are used to fix chairs and rails to sleepers. This is done by inserting the bolt through a hole found on the sleeper and the fanged nut bites the lower surface or the sleeper. These bolts are resistant to loosening, even with constant vibrations and rail movement and are known to be more effective than the screws and spikes.
Rail Nuts
The Philidas nuts and similar other nuts are crucial in terms of fastening the railways together. Combining the nuts with the necessary bolts is a must to join the rails and securely fasten the track. When used together, the Philidas nuts and the bolts are used for the following:
Works as the connecting and fastening pieces of fish plates that passes through their holes and makes the two steel rail pieces join together seamlessly.
They are considered the main components in terms of proper and correct railways fastening.
Workers who manage the railways and install these fastening parts must know which screws, bolts, nuts, etc to use. Combining and mixing two different parts that do not fit well together can result in accidents and potential derailing of a train. Do your research and familiarise yourself with the installation process of nuts and bolts, there is more to learn than just fastening everything together.
