Transport

Transports are elevator-type gimmicks, that are platforms usually colored blue and red with pair of wheels set on them. Transports are set either against the wall or between the walls. The player has to perform Spin Dash in order to make wheels to rotate and move the platform.

Transports first appeared in Sonic & Knuckles and has made several appearances in the series. The calling name, that platform gimmicks has been given is only mentioned in Sonic 3D Blast.

Sonic & Knuckles
At their first appearance in Sonic & Knuckles, elevator platforms are only seen in Lava Reef Zone Act 1. They are grey motors with pair of metallic wheels on each side. These platforms can be found on above or bottom of deep holes, while the wheels are set on roller chains between the walls. These platforms are only way to reach on the top or bottom of the deep hole.

When the player jumps on it, he/she can either stand to the left or right direction. he/she has to then perform the Spin Dash on the platform, which makes metallic wheels on the platform move. Depending which direction is standing when starts to Spin Dash, the left direction makes the platform to land, while right direction makes the platform rise up normally. This is a very decisive, depending when usually the player finds the platform above the deep hole from right direction or on the bottom of hole from left side.

Sonic 3D Blast
In Sonic 3D Blast, Transports are blue colored platforms with wheels, which are only featured in Volcano Valley Zone. It is only used to reach to the top of taller rock tabs. When the player jumps on them, the player has then perform the Spin Dash normally on the Transport to make it move up. However, if the player stops using Spin Dash, it makes the platform falls down to the ground. If the player slips below the falling Transport, the playable character will be crushed.

Sonic Blast
Transports in Sonic Blast are loosely similar to ones from Sonic 3D Blast, except now being smaller and having red wheels on the platform. They are only featured in Red Volcano Zone Act 2, where they are set against the wall. The player has to use them to reach to the top or slowly descend into the bottom of the hole. While Sonic has to use them, Knuckles can ignore them and climb up on walls.
