I don't honestly know how you end up with such perfect situations to create trackworks like that!
I often have to do a lot of terraforming in order to fit something like this in, It is worth it though because they look cool and are a really good way of getting heavy trains up a hill in a small area quickly. This one didn't require much terraforming though because it lies between two mountains so I could easily bridge the gap and then turn the tracks back under the bridges.
We really need PBS in OTTD before something like that becomes useful,
You only need PBS if you had a crazy junction like I have, you can build turnbacks just as easily without PBS
Any more like that?

Yeah, all on the same line. It takes an awkward route
This one is right near Prenfingley terminus and is really new (about 2 or 3 years) even though the line has been open about 55 years. The old line was a single track from the tunnel portals to the bottom of the slope and just nearly straight. There were a succession of steep slopes that caused problems with slower diesels. To increase capacity into the terminus the line needed doubling for these last 20 tiles so it was decided to eliminate the really steep sections of line.

The other big spriral is at Grenningstone. The mainline crosses itself 3 times to climb 7 tiles of height. The small spiral on the far left was an addition in the last 10 years (the line here is 62 years old) when this section was doubled and really steep gradients eliminated. The line used to just go from the tunnel portals at this spiral straight to the pieces of track that disappear off the edge of the shot. It was really steep
