Every different color on this map represents a different track gauge in a different country.

这张地图的每种不同颜色代表不同国家/地区的不同轨距。

Now, you can actually switch the gauges of trains but it’s massively inconvenient.

在，您实可以切换火车的轨距， 但这非常不方便。

And so from the outset, the Great Western Railway was built according to this wider gauge.

因此，从一开始，大西部铁路就是按照这种更的轨距建造的。

You’ll notice, on the map, that Spain and Portugal have a different gauge than the rest of Europe.

您会注意到，在地图，西班牙和葡萄牙的轨距与欧洲其他国家不同。

But Brunel, who had a very magnetic personality, sold this concept, the broad gauge, to the Great Western Railway.

然而，拥有力个性的布鲁内尔成功说服了大西部铁路公司采纳这一概念——轨距。

And it would have been better for trains had that wider gauge become standard, would it?

如果更的轨距成为标准，对火车来说会更好，不是吗？

But in practice, modern railways have generally developed using smaller gauges than seven foot.

但实，代铁路普遍采用的轨距小于七英尺。

Its top of the cab height is 14,3 ft and width over tracks is and width over tracks is 10,4ft.

其驾驶室顶部高度为14.3英尺，轨距度为10.4英尺。

Oh, I'm not buying anything. They're having a lecture. H-O gauge railroading." Half the size of O-gauge, but twice the fun." Very controversial topic.

我什么都不打算买 它们那儿要办一个讲座 HO轨距: 玩具火车的轨距 约为八分之五英寸 " HO轨距的铁路发展 O轨距一半的尺寸 却能带来双倍的欢乐" 非常有争议性的题目。

So George Stevenson just takes the gauge that's in front of him and puts a locomotive on it.

于是，乔治·史蒂芬森只是采用了眼前的轨距，并在面安装了一台火车头。

All trains stopped there, regardless of where their riders were destined, because Spain and France used railway gauges of differing sizes.

所有列车都停在那里，无论乘客的目的地是哪里，因为西班牙和法国使用的铁路轨距尺寸不同。

After processing the tubs left  the pit head to fill the large Chaldron wagons on the standard  gauge railway ready for dispatch.

处理完桶后，它们会被送到矿井口，装入标准轨距铁路的大卡德隆货车，准备发运。

And the standard gauge for coal wagons in the northeast of England was about four foot, eight and a half inches.

而在英格兰东北部，煤炭货车的标准轨距约为四英尺八英寸半。

And at four foot eight, what that means is that the boiler has to be carried up high, well above the chassis.

而在四英尺八英寸的轨距下， 这意味着锅炉必须被抬升到很高，远高于底盘。

The colliery engines are maintained  here and can be seen demonstrating the movement of wagons from time to time  on the standard gauge track bed.

煤矿的发动机在这里进行维护，不时可以看到它们在标准轨距的轨道演示车厢的移动。

And that is why the Stockton and Darlington Railway opened in 1826, and Liverpool and Manchester Railway opened in 1830 both have gailed at that spacing.

这就是为什么斯托克顿与达灵顿铁路于1826年开通，以及利物浦与曼彻斯特铁路于1830年开通时，都采用了这种轨距。

You don't know the half of it. It was billed as a lively give-and-take on the merits of model train sizes.But it was actually a setup to intimidate weak-minded spineless rubes into buying H-O starter sets.

你是不知道呀 本来宣传的是说今晚将会是个 针对模型火车体积的优劣而进行的场讨论会 可实只是为了唬那些 没定力的乡巴佬去买HO轨距的入门级火车。

Naturally brilliant engineer, and he grew up working with steam locomotives, building steam locomotives, to run on tramways on rails which were set four foot eight and a half inches apart.

天生才华横溢的工程师， 他从小就开始与蒸汽机车打交道，亲手制造蒸汽机车， 使其在轨距为四英尺八又二分之一英寸的轨道运行的有轨电车驰骋。
