You see it on the GoldenPass Express, using Stadler panoramic coaches with adjustable wheelsets. The system uses automatic gauge-changing stations that align and lock the wheels for each track width. You travel across regions with different track standards in one ride. This keeps speed, safety, and comfort steady while saving time and cost for operators. . .via :"
