At somepoint probably yeah. Unfortunately, it does seem that Amsterdam-Berlin seems to be pushed for a lot, and I fear for that poor decision fucking up the rest of the raillines.
An Amsterdam-hamburg-berlin line makes more sense imo, especially when you push it more towards the north as it doesn't cut the countries in half. It also gives you possibility to expand both north towards scandanavia, which you can extend further south to the rest of europe, or eastern europe through berlin.
But I doubt that will happen, because that is a bit slower than through hanover
I personally like it, although it is good to check what the optimal place of the stations is. It should be both benefitial to the North of Germany and the North of the Netherlands, and connect as many people in that area. So maybe you'd need an additional station near Oldenberg or Bremen to not skip over too much of east Germany.
If you also place a High speed line south from Amsterdam-Essen-(further south like) and Essen-Hanover-Hamburg, you have most of that area covered.
But my guess is that they'd build an Amsterdam-Hanover-Berlin line, especially when they don't plan ahead.
