Yes.
The frustrating thing of course, is that even if the trains are severely delayed, they have (or had, depending on whether they go out of business soon) a policy of running the exact schedule for each train as if normal. So even if all the trains are piled up, delayed, they would make local stops, etc. even though everyone wanted just to get to the end by express.
Sad that this kind of issue was so common (1x per month at least) that I blame them for not having efficient accident backup plans.
Yes, yes, I realize that there's the problem of having trains go express when they're all stacked up.
