騎鐵馬進入風景秀麗的后豐鐵馬道後，令人心曠神怡。后豐鐵馬道自從94年4月17日開通啟用後，遊客絡繹不絕，貫穿舊山線的「9號隧道」及「花樑鋼橋」更是絕對要停留打卡的地方。在花樑鋼橋上，不但可見到灌溉北臺中地區的葫蘆墩圳入水口，別有意義，全長5.8公里的鐵馬道也與「東豐自行車綠廊」相接，形成深具懷舊魅力的自行車專用道。
來到后豐鐵馬道騎車，沿途景觀多樣，除了青翠田園與寧靜的鄉村景緻外，更可模擬體驗古老藍皮平快車開進隧道後既幽暗且陰森的感覺，一出隧道口，又馬上感受到橫跨在大甲溪寬廣溪谷上的驚嚇感，充滿感官的刺激，絕對值回票價喔！
觀察九號隧道北道口及南道口上的文字，寫了什麼呢？與它合影吧！
We are at the north entrance of Tunnel No. 9 now.
我們到九號隧道北道口了。
I heard that the Houfeng Railway was renovated by the old mountain line, and Tunnel No. 9 used to be a tunnel that trains would pass through.
我聽說后豐鐵馬道是台灣的舊山線整建的，九號隧道以前是火車會經過的隧道。
I see. Look ! Is there any writing on Tunnel No. 9?
原來如此，看！九號隧道上是不是有字？
Yeah! Can you see what's written on it?
真的耶！上面寫了什麼？
It seems to be " shixie qianxing bu zhi."
好像是「潛行不窒」。
I heard that the south entrance has a word, too?
聽說南道口也有字？
I know, it seems to be " qi xiang xiong shen "
我知道，是寫「氣象雄深」。
Can we take a photo together?
我們一起拍一張照好不好？
OK! 3 2 1, say“Cheese”.
好啊！3 2 1 笑。

小朋友，你知道隧道口兩旁的「潛行不窒」及「氣象雄深」是什麼意思呢?
潛行不窒：是指潛入水底行走而不窒塞，這裡是說火車潛入九號隧道後，行走非常順暢而不會感到阻礙。
氣象雄深：是指氣勢雄渾深沉，這裡是形容大甲溪鐵橋兩岸壯麗雄渾的景緻，令人震撼。
上網搜尋大甲溪水力發電的設施並相互討論與綠能的關係，記得紀錄在旅行筆記喔！
This bridge is so beautiful !
好漂亮的橋！
Yes, it is called the Hualiang Steel Bridge. Looking from a distance, you can feel its majesty immediately.
是啊！這是花樑鋼橋，遠處觀望，就能感受到它雄偉的氣勢喔！
Look!The river under the bridge is also beautiful. What is the name of this river?
看！橋下的河也很美，這條河叫什麼名字呢？
This river is called Dajia River. There is very little man-made damage, so it is limpid.
這條河是大甲溪，很少人為的破壞，所以很清澈。
Mention of Dajia River, do you know that there is a hydroelectric power plant in Dajia River?
說到大甲溪，你知道大甲溪有水力發電廠嗎？
I know, hydropower is a type of green energy, which is better than fossil fuel power and protects the earth more.
知道，水力發電是綠能的一種，比化石能源發電好，能愛護地球呢！
Wow! You know a lot!
哇！你懂得好多！
Hahaha, of course! Let's do reasearch on other green energy together!
哈哈，那當然！
我們一起再來研究其他綠能吧！
