You're right. It does, unfortunately without citing any sources of its own.
In Europe, freight rail is less than a quarter that of the US, while passenger rail is much higher than in the US. Where tracks are shared, passenger rail generally takes priority in EU, and vice versa in the US. When reading about European railcar crash standards, I found no evidence that modern design standards include any requirements on crashing into freight trains. Just generic crumple zone requirements.
