Understanding the Construction of Railway Tracks

Railway Tracks

Railway TracksTrain tracks are fundamental to any railway construction and represent the distinction between this type of land transportation with others because it has a fixed guidance system.

The track is the obvious part of a railway construction, but there is a sub-structure that also provides support. This is just as important because it makes sure that passengers are safe and comfortable throughout the ride. The width across a two-track alignment is approximately 15m for a modern formation. Rope and Rail Ltd. agrees that the use of quality iron and materials for the tracks keep them sturdy, last longer and reduces the risk of accidents because of rust or breakage.

Rail & Track

Engineers use different methods to construct railway tracks. The usual track form has two steel rails secured on crossties or sleepers. This makes sure that the rails are at the correct distance from each other and can bear the weight of the train. The sleepers have a measurement of 650mm to 760mm space intervals between them, but it will depend on the railway’s requirements.

The “flat bottom” rail is the standard form used all over the world. A rail normally rests on a cast steel plate which construction workers screw or bolt onto the sleeper. Clips or clamps attach the rail to the plate, depending on the design.

Brakes

The air brakes protect against the chances of runaway trains, rare as they might be. This particular part of a train prevents disastrous accidents from happening.

A train’s air brake is similar to the brake of a car. While driving a car, hitting the brake pedal transfers foot pressure to a piston, which clamps pads tightly over the brake disk in a vehicle’s wheel. The air brakes of a train also use pressure to stop; instead of brake fluid, the system uses compressed air.

These are only some of the parts needed and used during the construction of a railway. A project requires only the use of quality materials to ensure safety and long lasting use.

The Proper Way to Use Concrete Breaker

There are many types of concrete breakers, though. Some are no bigger than a home electric drill that can be handy in some situations. For instance, if you plan to re-plaster your wall or you want to re-pave your old concrete path, a small concrete breaker hire can make work go more smoothly.

Sure, you can buy your own concrete breaker, but it may be more practical to hire one for the occasion. You should have no trouble if you use it properly.

Here are some suggestions:

Start from the edge

Most people like to dive right into the thick of things, and start breaking up the concrete in the middle. Smaller concrete breakers will not be affective if you try to do too much at once. The best way to break up concrete so that you use less power and effort is to start near the edges. Avoid frustration and start small. The job will get easier as you get to the middle.  If your concrete path is more than 4 inches thick, a concrete breaker with 1250 watts of power will not work for you. You have to hire a more powerful machine that you can handle on your own. Ask a reliable company for suggestions.

Use the right tool

Concrete breakers work with several types of chisels. The most common is a chisel point, which you can use to break up concrete. There are also chisels with flat heads that are more suitable for dividing the concrete along a line, removing tiles from a concrete floor or removing plaster from a wall. Do not use your concrete breaker to pull up slabs of concrete, as this will damage the machine. Use a crowbar instead.

Concrete breakers work best on concrete, though it may also work on ceramic tiles and plaster. Do not use it to break up timber flooring. It will damage your chisel and the concrete breaker, and it will not do the work.
