Can a Train really flatten a 50c coin?

[buddy92]

As title, can it?

[Neale]

sure can, trains are heavy

No, it will vibrate of the track...

[Jack960]

Yeah put any coin on the track and the train will roll it out. Ive never done it personally but know its been done and seen the coin after. The coin shears as the train wheel hits it, it will keep rolling it out until the wheel can get over it.

Dam younuns got no idea most of the baby boomers would have spent numerous hours getting coins flatten by passing trains if various sidings before we got all OHS and soft , or scribbling unledgeable writing on trains

[JimStone]

Sure will, can even flatten a .22LR and not go off too.....

[79FordEsky]

Or you can put it on a tram track

[Nova 8]

I got taken home by the cops for flattening coins on the train tracks when i was about 10... and they took the coins....

Bah, you and your coins, us gen X'ers used to chuck rocks at the freight trains

And drop those bush/pigmelon things onto them from the bridge

[Cashie]

Used to do it with trams out the front of the school.
We got more and more game putting more coins on each day until the tram drivers wised up and one day stopped their tram and claimed all our coins.

[blueoval]

I was told the coin would derail the train so grew up not trying to flatten a coin.

Hmmm...

[Pinkbits]

You should see what they do to cars then.
Detonators are fun too, all part of my job.
Don't know if you're serious or trying to be humorous.

i put a 20 cent on the track in front of a coal train once. after the train passed the 20 cent was about 50mm across and paper thin. could still see that it was a 20 cent though. although very distorted, battered and bruised, the images on the coin could still be worked out even though the coin was squashed smooth.

hmmm. i wonder what i did with that coin, had it for years.

yes it will been there done that steam engines are best lots of weight in those boilers

Me too, this is an outrage.

I know what I'm doing next weekend tee hee.

[zilo]

when i was a kid we used to take 2c coins and place them on the track.
train would flatten them to perfect 10c size.
we would then go to laundromat, put in machine and get two 5c for it.

after a while we had enough for a day at luna park...(7c a ride)


our house backed onto railway tracks in suburban melb so we could do it all day....

[buddy92]

7c a ride?

Man now I feel young ( I'm 20, thanks for making me feel it again! )

that most have been a while ago. long time since you could buy anything for 7c.

stealing all those 5c you proberly sent the laundromat broke

I don't really want to flatten my coins but does anyone actually think a coin can derail a train?? I'm struggling to believe that it can although happy to be proven wrong.

[Pinkbits]

There is no possibility of a coin derailing a train, although they can cause other inconveniences.
I have seen other methods that have been tried over the years but won't go in to detail here.
Let's just say that an engine block & shopping trolleys to name two, did'nt succeed.
You'd be surprised the lengths that theses idiots go to for a cheap mindless thrill.
As if train driving is'nt stressful enough.

I've done it heaps of times...they tend to flatten more on one side than the other, but they don't vibrate off the track. A loaded coal train weighs 10,000 tonnes all up, however, after the first set of wheels goes over the coin, it will fall off the line, so it only has the 120 to 130 tonnes of locomotive squashing it.

Many people think a wheel on the track is a "flat steel surface pressing on a flat steel surface"...it isn't. The rail head is slightly convex, and the wheel itself slopes from a larger diameter at the inner edge near the flange, to a smaller diameter outer edge. This allowed the wheel to ride up the rail and in effect give a differential effect in a turn...one wheel will be riding on the "smaller" portion of it's diameter and the other on the larger portion, allowing it to go around the curve without skidding one wheel. So it isn't like putting a coin under a press between two flat bits of steel, it's way more complex than that.

NOW, the disclaimer...I work driving trains, I know all the safety and distances and safe working rules and regulations.

I am NOT a numptie walking into the rail corridor to lean down in front of an approaching train and put a coin on the track. Do not do it, we will turn you into paste. Besides the fact that if we see anyone in the corridor who doesn't belong, the police get called, and you have some heavy explaining to do.

2011G6E do you work on ARTC in NSW?

LOL I got the same lecture But What does this say about a simpler time ? our parents were more worried about a train derailing than us kids getting flattened by a 200 ton + Train for messing around in the rail yards

[2011G6E]

Nope, I work for QR National in central Queensland driving the coal trains.

Seriously...don't **** around the train tracks if you don't belong there...the number of ways you can die are numerous and staggering. Come within a couple of meters of the overheads and the 26,000 volts can arc across and cook you, try and climb around wagons that could start moving and slip and fall, and yu'll be minced. People don't realise the energies involved...doing 70 to 80kph and hit a massive big roo, and it just goes "thud" (followed by the sound of laughter from the drivers... ).

I'd like to see the maths worked out of the forces concentrated on that little point of contact between the steel rail and the steel wheel...it's only a tiny contact patch, and with 130 tonnes pressing down on such a small area, the figures must be staggering.

Waiting for the Gunzles to come out in force in this thread!

[4stanger]

I agree with 2011G6E, ( I also work with QRNational)
A train will flatten any coin.
Don't believe this?
Don't try it, stay away from the trains & tracks, there is danger!
Ask mythbusters to do it ;)

Used to tape two half pennies on top of each other on the track out side my home in Medlow Bath NSW. The force used to meld them together. Still had them plus some pennies in a jar up to a few years ago but they went in my third house robbery.
