Where's the power comes from !

你知道吗？英国的火车是靠哪来的电力开动的呢？
（应该不会有人以为是用烧煤炭的吧？除了。。。）
你可能不知道那是靠第三条铁轨来传电的吧！
之前一连串的发生有人堕落轨道中被电灼伤！
灼伤还事小，还有人在轨道上小便被电死！
讲镇，如果不是这几件意外，我真得不知道 在拿行行列列的轨道中，有一些是带电的！
好了，怎样分辨那一些 是带电的轨道？那一些不是呢？
一方你万一不小心掉了下去。你也可以避过那些带电的轨道！
仔细一看，在3条轨道当中，就会有1条的表面特别的光亮，
这就是因为要用来过电的！
所以表面特别的光滑，下次看到了，不要踏上去哦！！
还有一个朋友告诉我的贴士，
下雨天，不要跑道月台前甩雨伞上的水，
哪怕是万分之一的机会，电子会通过水跳跃到雨伞，
而雨伞的柄又是铁做的！那你可能就会oh oh liao loh..~~

Do you know how a train (I mean British train) power up their engine??
( I dun think there is anybody will say is by burning charcoal guah…kekekek)
U might not know that it is actually conducted from the 3rd track of the rail.
Recently there had been a few cases whereby people falls on the track and was burn badly.
Another serious case was a man was electrocuted when he was peeing on the track!
So, how to differential which track is carrying power?
Just in case u accidentally falls on the track, u will be able to identify it and avoid those powered track.
Look carefully on the track and u will see 1 tracks which has a really shinning surface, that was the track that carrying the power!
The shining surface is to provide a good conductivity to transfer the power!
So next time , pls avoid the track with shining surface !
Another small tips from a friend,
Pls do not shiver the water on you umbrella from the platform to the track,
There might be a really slight chance that the electron might jump thro the water to the umbrella holder which was made by metal!
If that’s happen…u will know the consequences…..
