They were traveling by train for some time. I could see that in tracking ...
If I'm not mistaken, mine went most of the way by plane. And if I interpret the cryptic tacking information correctly, they reached Germany about 2 weeks ago. Frustratingly, the tracking system no longer seems to reveal any details beyond that. It keeps repeating the same Chinese phrase which is then translated as "Arrive at the Sita processing center" where it used to give locations (like Frankfurt) and differentiate between customs processing, customs clearing, processing, etc.
