The second train crashed on a non-high speed part of the network.
There is also no reason to treat speed limits on high speed and normal trains differently. There are plenty of speed related crashes on low speed lines. If anything the stakes are even higher on commuter trains because they tend to carry more people, many of which will be standing, and are more likely to crash into another structure as was the case in the Japanese incident mentioned.
That's still an issue of design though. I am pretty certain that this would not have been possible in quite that way in Japan.
Your comment is down thread of a comment containing a link to a Wikipedia page of a Japanese train crashed caused by speeding. I do not understand how can you think this is impossible in Japan.
