Railroad brake stick

Used railroad wheels

The development of the wheel-rail system has led to the adoption of the conical profile of the running surface of the wheels, which in turn led to the appearance of an effect known as loop movement.

In case of excessive overheating due to a hot casing or a blocked brake, the paint burns with significant smoke generation. When it cools down, very visible peeling and color changes appear.

With the wheels mounted, four marks are painted on each wheel to check if they are still properly aligned. On the Rhaetian Railway, on the other hand, the black and white paint accomplished the task of more easily identifying the wheel lock. Due to the influence on the operation of the vacuum brake of height differences on the routes traveled, and especially in winter with snow and ice, there is a particularly high risk of the brake locking the wheels.

An advantage of the rims is that with worn wheels, it is not necessary to replace the entire wheel disc. Therefore, it is not necessary to release the existing pressure connection between the wheel disc and the axle. Since each wheel rim can travel on average more than 600,000 kilometers on very hard steel rails, it must be made of particularly strong steel and be firmly attached to the wheel hub. A disadvantage is the higher mass of this type of wheel, due to the amount of material required to ensure the correct fit of the wheel body and rims; to give stability to the press fit between axle and wheels; and due to the considerable minimum thickness of the rim itself.

How train wheels work

And I’ve been reminded of it by work-related issues. The Inland Rail, a rail project to link Melbourne with Brisbane through the interior instead of the coast. As I was reading the article I was thinking that, non-stop and rough, it was like a Malaga-Valencia… and suddenly I read that it will save “10 hours of travel time”. But where are you going, you mule cart transporting the containers?  Well, a Malaga-Valencia nothing, it turns out that it is triple the distance: no less than 1700 km. Take a look at the video and you will be amazed with the transport of goods in Australia.

It has caught my attention that they are worried about the possibility of getting electrocuted by the catenary. I don’t know how realistic it is, I have the feeling that you would need a very long selfie stick, at least in the Shinkansen stations, as you can see in the following image.

Ok, the first competitors have inertia and can’t stop so easily; it’s difficult to determine when is the limit between inertia and competitiveness… but the asshole in red (because he has no other name), who passes when the cop has them all stopped, I would give him a cigar that he would remember all his sport career.

What are the wheels of the train called?

Railroad sleeper, also called railroad crosstie or railroad crosstie, is a rectangular support for rails on railroad tracks. In general, the railroad sleeper and rail fastening system fix the rail together. Rail ties should support the rails and keep them spaced at the correct gauge, and also transfer the loads to the track ballast and subgrade. Rail sleepers must have a certain flexibility and elasticity, which is neither hard nor soft. When the train passes, railroad ties can deform adequately to cushion the pressure, but after that, they should recover to the original shape as soon as possible.

Railroad sleepers were originally made of wood, wooden sleeper has such characteristics as elasticity, light weight, simple manufacture, good insulation properties, fasteners simply connect to wooden sleepers, and it is easy to lay, maintain and transport. In addition, there is a higher coefficient of friction between the wooden sleepers and the ballast.

The steel railway sleeper is formed of pressed steel and with a channel-shaped section. There is a housing for the rail fastening system that is welded to the top of the steel sleeper. Because they are stronger than wood and cheaper than concrete, steel railroad sleepers are generally considered intermediate between the wood sleeper and the concrete sleeper. It seems that the steel sleeper is a better choice, but steel rail is applied in some areas such as secondary lines in the UK, much less than other types of rail sleepers. The facts showed that steel rail is easier to adopt for special rail section, for example, Hejaz railroad in Arabian Peninsula.

Plastic railroad sleeper, also called composite sleeper, mainly refers to the railroad sleeper is made of plastic composite. Plastic composite is a totally modern material for making rail sleepers. It is the mixtures of plastic and used or discarded rubber. The plastic sleeper combines the flexibility of wood and the durability of concrete, at the same time, some shorts of other types are avoided. Plastic sleepers were first used on the railroad in Japan, which is the leading manufacturer of composites. After that, plastic composite sleepers were installed on the tracks of the Zollamt Bridge in Vienna, Austria.
