The Internet has many places to ask questions about anything imaginable and find past answers on almost everything.

Can you survive under a train?

So the answer is yes – it is possible to survive lying under the oncoming train, but it is very unlikely that you could survive that without a major injury. It is a good idea to stay away from railroad tracks. Just by hanging around such places you are putting yourself in danger.

Can you die from touching train tracks?

Nearly 50 people died in Britain after trespassing on live railway tracks last year, figures show. The company is concerned that people do not realise they can be killed by simply touching one of the rails. …

Do hobos still exist?

When you think of hobos riding the rails across America, you probably think of the Great Depression or other bygone eras. Yet you may be surprised to learn train-hoppers are alive and well in modern-day America — and, what’s more, around the world.

What is the longest train ever recorded?

The record-breaking ore train from the same company, 682 cars and 7,300 m long, once carried 82,000 metric tons of ore for a total weight of the train, largest in the world, of 99,734 tonnes. It was driven by eight locomotives distributed along its length to keep the coupling loads and curve performance controllable.

Why is one locomotive always backwards?

Making all that commerce move down the track are train locomotives. But some of the locomotives face backwards as they move down the tracks, seeming to one 2News viewer that they are being inefficiently dragged down the tracks. Thus, the direction of the locomotive makes no difference to efficiency or safety.

Are steam locomotives more powerful than diesel?

According to the designers, diesel engines could run faster and work longer than steam locomotives. Instead of generating steam in an enormous boiler, the diesel burned oil to power a generator that, in turn, powered electric motors on the wheels. Locomotives, in comparison, had a low thermal efficiency.

Could steam locomotives make a comeback?

Instead of making improvements in the existing steam technology, engineers were more attracted towards its replacement by diesel or electric traction. However, with the help of the scientific advancements in the past, the steam industry can be revived today and operate at its full potential.

Do locomotives have toilets?

Yes, all over the road locomotives, and local use locomotives are equipped with toilets in small rooms in the front hood area of the locomotive. Some have an air pressure assisted flushing system using fresh water similar to an airline toilet.

Why are steam engines not used today?

The reason we do not use them for transport is that they take too long to get started and build pressure in the boiler to drive the pistons. Plus they are generally less powerful than an internal combustion engine (lower cylinder pressures = less torque) and more bulky/heavy. In short, they are not very convenient.

Are steam engines still in use today?

Steam-power isn’t as outdated as you might infer from its near extinction in the developed world. Today, there is still one steam locomotive operating on a Class I railroad in the U.S., the Union Pacific 844. For the most part, though, the U.S. and the rest of the world have converted to electric and diesel.

What is the most powerful steam locomotive ever built?

Union Pacific locomotive

Can Steam be hotter than 212 degrees?

Q: Is it true that water (steam and ice) can not get hotter than 212 degrees and colder than 32 degrees? It is not true that water can only get up to 212 degrees and as cold as 32 degrees. After water changes from a liquid to a gas (at 212 degrees Fahrenheit) it can actually heat up much hotter than that.

Is Steam a gas Yes or no?

Steam is considered a gas. It’s as you probably know vaporized water. It’s no different than other liquids that change state to a gas.

Is steam hotter than fire?

Water in an open container can’t exceed about 100 °C because it just boils and floats away as steam. Water in a strong, closed, pressurized container can be as hot as fire or hotter. Water evaporates at around 100 degrees Celsius. Anything can be hotter than fire in the right conditions.

Is Steam a vapor or gas?

All steam is water vapor, but not all water vapor is steam. Water vapor just means the gas form of water.

Is Steam a Vapour or gas?

Steam is the vapour obtained by heating a substance to its boiling point and as such is “hot”, or better at boiling T. Vapour is the gas phases in equilibrium with a substance, or the part of it which escapes in an open system.

Is Steam an aerosol?

Steam that is saturated or superheated is invisible; however, “steam” often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapour condenses. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion.

Can water steam without boiling?

That means, to produce steam, you need to boil water, so it changes its phase from liquid to gas. However, scientists are proving that it is possible to produce steam from water without boiling it – simply by supplying the latent heat necessary to change the phase.

Why can we see steam but not water Vapour?

Unlike clouds, fog, or mist which are simply suspended particles of liquid water in the air, water vapour itself cannot be seen because it is in gaseous form. When water is boiled the water evaporates much faster and makes steam. Steam often has droplets of water, which is what is seen water is boiling.

Which is hotter boiling water or steam?

Boiling water is a saturated liquid vapor mixture but steam is either a saturated vapor or a superheated vapor. Steam can be superheated only when the applied temperature is greater than the saturated temperature for a given pressure. Hence steam is always hotter than boiling water.

Can we see water Vapour?

Gaseous water, or water vapor, isn’t something you can see, but it’s part of the air around you. Under normal circumstances, water vapor enters the atmosphere through evaporation and leaves by condensation (rain, snow, etc.). Water vapor also enters the atmosphere by a process called sublimation.

Is Steam a superheated vapor?

Dry steam is saturated steam that has been very slightly superheated. If wet steam is heated further, the droplets evaporate, and at a high enough temperature (which depends on the pressure) all of the water evaporates, the system is in vapor–liquid equilibrium, and it becomes saturated steam.

At what temperature is steam superheated?

100 °C
