Trains take a Mile to stop.
Some ships take many miles to stop.
Fully laden Trucks though, they can stop as quick as any micro-mini, so nay worries then?..
Same with Trams that share road space, they MUST be able to emergency stop the same as a Bus, or we wouldnt allow them on the road?...
I dont believe any of that, because I know the truth...... I have driven the truth....
Well, ok, I dont drive Trains for a living, nor do I have a Train drivers licence..
But I have driven Leander and Mallard, old Steam trains, it was one of those "Do you want a go?.." moments when I used to volunteer back in my youth at a restoration project...
You dont say no, do you?...
An experience,.... and being able to hit the brakes, I know, they dont stop that easy.
Its not a pedal either, you can find reverse, slam the lever full, and then go wind the brake wheel, or get someone else to do one whilst you do the other... its team work.
And my experience was solo, no full line of carriages wanting to push the things to the end of the line.
So, can we get hold of that stupid out of date based on an old Ford Anglia Highway Code stopping distances much referenced piece of literary graffiti and put it to the test.
First of all, take older cars that are still legal on the road, and see what conditions require the stopping distances stated.
Anything will do, perhaps a Model T to cross thread that with another transport myth thread?...
I agree on a damp or wet road, maybe ice even, that the full stopping distance stated may apply... on some cars...
But Modern stuff?.
I have a car that can manage half that distance without it even being a mild case of something may be wrong?...
Then take a Articulated Semi cab unit and put that to the test, Solo, or Bob-Tail as you Yanks call it.
Then put the full 44 tons to test and see how that changes.
A Bus, Coach even, with full passenger load... get some Busters to replicate standing persons even.
Get a Tram, the ones you see in certain USA cities, and see what they can manage.
Get a Commuter train, Tube train even, they have crossings over the road, so lets see what one of them can do on full "Oh Shoot" brakes.....
What about a fully laden Iron Ore bulk transport train?
The show is friendly with Deadliest Catch, what can the Hilstrands do in Time Bandit from full thrutch forwards to dead stop?...
And lastly, get a hold of that friendly cruise ship and ask one of the captains what it can do.
Without spilling the water out of the swimming pool.....

Without spilling the water out of the swimming pool..... that could make an awesome hourlong segment, if one could phrase the myth properly, and get everybody to participate. we would definitely want to comapre modern braking technology with old braking technology - and also look at the effects of panic stops on the cargo. modern anti-skid truck brakes do an unbelievable job of bringing things to a stop - but it is still rough on everything inside. (our 100' aerial platform truck can dump speed as fast as a car, if the asphalt holds together.) |

Here we go, my own area of "expert"-ise, I can guide them on how to set up for a fail, use of the wrong straps, or straps instead of chains, and the like....
I have a suggestion.
Can they set up a rail, much like that rocket sledge, and guide a trailer down that to a sudden stop that doesnt destroy the trailer, then repeat slam a trailer into the stop with well secured and badly secured cargo?...
May I also suggest they remove the headboard from any trailer before they try...
Its going to come off anyway, better its done where you know where its going to land?...
I would say grab a 10 ton block of concrete and some basic ratchet straps and slam it into that stop... just stand well back away from it?.... it WILL fly....
Or just use those concrete barriers that have used before... get some old broken ones, because they wont be much use to anyone afterwards.
I am also going to suggest a line of scrapped cars at the sudden stop end.
For two reasons...
One as a shock absorber for all the loose cargo flying around, and two as a graphic example of what happens to flying cargo when it hits something.
....Three reasons, its gives them something to attach camera's to as well?....
My own solution, if in doubt, add another chain.

I know from personal experience that even at 30kph a normal car cannot outbrake a 4 ton forklift when the forklift driver decides he's had enough of the guy trying to kiss his rearbumper.

One to go along with this: It takes a battleship 5 miles to turn around, or some variation. If you have a large ship say a cargo ship or cruse liner, how large is their turning radius?
I know that the answer is going to be dependent on the ship design and newer designs are more maneuverable, still could be fun. Does Jamie get to go water skiing on a cruse ship again?

even the big carribean cruiseships that come for maintenance to Helsinki can make it through the gap at the suomenlinna fortress, so that one is most definately busted. They do however have special pilot-captains for that bit. This should NEVER be attempted by italian captains at the very least  |

They do however have special pilot-captains for that bit. This should NEVER be attempted by italian captains at the very least cruise ships are specifically built to be maneuverable in close quarters, as I recall. Newer military ships are probably also made to be more maneuverable - but I would guess the myth revolves around post WWII battleships. I do know from anecdotal stories from a family friend that they are not exactly turn-on-a-dime, and that there is a proportional relationship between their length and their turning radius. |

This should NEVER be attempted by italian captains at the very least It's surprising how small a wake it makes. and it looks like a fascinating place to visit - but I was trying to figure out which channel is "the gap" because the angle of the video didn't make it look like it was so much a tight turn as just a narrow channel.  |

it's the channel at the very bottom, and they have to make a sort of s-turn to get through as there is shallows on both sides.

That may be highly outdated.... I have seen battleships swing around at a speed you dont think capable, but that was modern stuff, and a general alarm is sounded first, or its noted that its on manoeuvres, to stop the cooks sloping the daily soup all over the first officer?... Here is a USA one doing it in a couple of hundred yards.... maniacworld.com/battleship-makes-a-sharp-u-turn.html(Site "safe") Note the angle of dangle as it leans 'out' of the turn?... |

I think the nelson class is still my favourite battleship style wise, there's just something about 9 forwardpointing 16 inchers....

I like modern battleships that have electronics that "lock on" to a target OTH and go ballistic missile on it.
One missile, job done, move on.

I bet you have ships that only do helicopters as well dont you?...
Over here, we are a bit tight for space in ports, so have multi-use battle ships....
