looking good, if your looking for adice i would reccomend rotating the camera slightly for the final render.
It might be just me but this section of the track confuses the eye. its hard to see which track leads of were and they kind of overlap at this angle. Once texture are applied it might be a non issue but i just thought i’d point it out
Z-Up doesn’t solve the issue. Even when trying to tweak the control points manually.
Tilting does fix the issue with the object that is at 90 deg to the world. Adding additional control points doesn’t help.
And no, I’ll not dive into geometry nodes 
That’s what I’m doing too. But was hoping for a more elegant solution.
Mine works as intended
I see u are using Path curve, if I’m not wrong, that could be why yours is acting like that
Interesting.
To make the rails, I use a collapsed box and extrude the vertex, using snap to grid.
With the rough path outlined, it is converted into a NURBS curve. But then Z-up as Twist-method doesn’t work. And with “Minimum” I have to adjust the tilt manually.
However - despite having this tried before (and maybe broke some settings) - I just converted the box > to curve > to Bezier curve approach again. And Minimum as Twist-method works.
Z-Up fails again. Which makes sense.
Curves are somewhat tricky in Blender. I don’t like them very much, to be honest, but sometimes there’s no other way. 
By the way, in the video, I didn’t use Z-up either.
You are right. But it was not intended to be the final camera-position.
Wow with a tunnel!
Is this of any use? By chance saw it, and only recently posted.
ohhh - a new can of worms
I wasn’t planning on animating this coaster, but now…damnit, now I simply have to try 
That is absolutely adorable and the lights, chef’s kiss! Great job all around. Love the animation as well.
OMG! This is amazing! You even have ppl. And the lights. You win
Not sure I can finish mine… IRL these days 
Need to finish the columns, some assets and animate the speed.
Well I’ve tried to animate the instances of the lights with a time delay, but I haven’t found a way yet.
Maybe a bit of motion blur… (in the tunnel?) - Just a thought.
