B since all movement is relative.
This was a triumph.
Violates conservation of momentum unless the portal/train slow down.
Yes, but portals violate basic physics anyway.
A portal that faces downwards into another portal is effectively a perpetual motion machine. Drop a ferromagnetic object into the loop and wrap some wires around the loop, now you have an infinite electric generator.
