I was hoping that the railway modeller was going to switch the points after the first train was all on the spiral. That would have sent the train back on to the fly-over and round the loop ad infinitum.
Thank you for sharing a “wonderful thing”… though I do feel a little bit queasy now. Maybe watching at double speed wasn’t a good idea.
Just some info from a fellow model railroader. This “helix” as they are called are typically vertical in nature, allowing the trains to move from one level to another. Some model railroaders, since they are pressed for space, will have one level over another (like bunk beds) to double the amount of real estate in the same space.
Also, it’s normal to have multiple locomotives spread out within a consist of cars to spread out the traction - just like in the real world.
