All the Russia conspiracism in here reminds me of the claims that they blew up their own pipeline. The cost/benefit analysis of that situation was so obviously out of whack that no serious person should could have considered it to be a possibility.

This case is more plausible than that one was, but not by much. How could the benefit from derailing a few trains possibly justify the risk of A) more sanctions, and B) triggering NATO's Article V? The benefit of these operations is what, slowing trains down by one day? The 2022 sanctions on Russia have lowered their GDP by 6% by some estimates, which is the equivalent of turning the entire Russian economy off for three weeks of the year, every year. The notion that Russia would risk war and/or crippling sanctions to mildly inconvenience a tiny share of rail customers in The Netherlands is simply absurd. Putin makes plenty of mistakes, but he remains a shrewd adversary, and he is certainly not stupid.
