This stage is similiar to Pumpkin Hill, but set at daytime, with no ghosts and railways circling the stage.
This section requires an expansion.
Story
Shadow must chase and find Tails'Cyclone before it gets too far.
Gameplay
There are many rails to grind on in this stage, as well as Propeller Springs. There is also a large area in this stage which is rather difficult to see.
Overview
Level Up Item
Shadow's Ancient Light Level Up Item is located here as an optional Level Up Item. This allows him to use the Light Speed Attack. Not far from the start of the stage, the player can see a Chao Container.Ā If one walks off the left edge of the platform, Mono Beetles will appear, and the player can use the Homing Attack to reach a Spring Beetle; the Ancient Light is found on the platform directly overhead.
Missions
Collect 100 Rings
To quickly complete this mission, the player should head straight down the main path and pop the Item Box accessible via the first Propeller Spring along the way. They must proceed forward until Shadow reaches a ledge with two adjacent Grind Rails and a Point Marker. The player should grind down these rails to reach a cliff with another pair of rails on the top, then proceed down the incoming extensive rail section which leads to a single Spring stuck to a mountain. Here, instead of using the Spring, the player should jump around the mountain by jumping down to the ledge below the Spring, where the second Chao Container is located. The player may have to perform a Homing Attack during the descent to reach this ledge. Here, there are two Item Boxes containing a total of thirty Rings. The player should climb back up the mountain and take the right rail after crossing the second Point Marker.
At the end of the rail, the player should jump and perform another Homing Attack to reach the Super Ring on the left in midair. The player can also collect the Super Ring on the ground and then proceed forward for more Rings.
If the player crouches when grinding down the rails and ignores any enemies that are not on the path, completing this stage in less than two minutes should be easy.
Clear Hard mode
This mission places iron balls on many of the rails. To get by them, the player must use the Grind Step.
Chao Container locations
Instead of taking the first rocket, the player should hit the Mono Beetle on the left to reach the platform where the first Chao Container is.
As the player reaches the Spring at the end of the second extensive Grind Rail section, they must perform a Homing Attack while pressing up and left on the control stick. They should then land on a ledge below the Spring where the second Chao Container is.
When the player gets to the first Propeller Spring, they must bounce to its peak and dive into a small alcove on the right using the Homing Attack. The final Chao Container can be found inside.
As soon as the player begins this stage, they will be grinding down a rail. When the player looks to the right side of the mountain, they can see some sort of steel device with a wheel at the end emerging from the mountain. Big's head can be seen where the device and the mountain come together.
In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, Sky Rail appeared as Sky Rail Zone, specifically in the "After-The-Credits" scene from Sonic Universe #62. Sky Rail Zone retains the same appearance as its video game counterpart.
Trivia
The beginning of the stage in the Dreamcast version is different in the GameCube remake. Noticeably, the platform underneath the rails with the 1-Up is missing.
In an early trailer of the game (shown at E3 2000), Sonic is shown in this level instead of Shadow.
If a treasure hunter character is used in this stage via glitches or cheats, they can obtain items here by digging, unlike in other non-hunter stages.
