I took the Puyoma train to Taichung yesterday for tomb sweeping.
I’m not sure what the puyoma train is intended to do (compete with high speed rail??) as it runs only twice a day. But what I notice is the train vibrates a LOT. Like it was traveling over rough roads or something. Not only that sometimes it seems the train tilts excessively, like more than say those push pull zhichang trains at similar speeds.
I heard there are a lot of controversy with those trains and some train attendants said the train used to be a lot smoother before.
I do not feel this at all. I prefer this train over others as it’s comfortable and modern. But buses can be faster and for sure cheaper than the Puyuma/Taroko.
Especially just north of Taitung Station. The track is not a dedicated one, so you’re using the same rails as other passenger and freight trains- the track is really not built for such high speeds. The train is supposed to be able to handle it- ‘supposed’.
