Ride rail

Ride rail, also known as ride-rail, are a mechanic found only in Splatoon 2’s Octo Canyon, as well as Splatoon 2: Octo Expansion. In Octo Canyon, they replace the inkrails from the first game in the campaign, while in Octo Expansion, both can be found.

Description
Ride rails act very similar to inkrails in that the player uses these lines of ink to travel and jump further in squid form, but they differ in the fact that Agent 4/Agent 8 can grind on the ride rails by turning into humanoid form, they can use weapons while riding, but ride-rails are one-way, in contrast to inkrails, which only allows the player to travel along in squid form but allows Agent 4/Agent 8 to travel back and forth.

Ride rails appear to be ropes of ink-covered metal spirals containing ink inside that connect to platforms or are suspended mid-air. It can be activated by the player's ink hitting a slightly larger bulb that is similarly looking to the inkrails bulb but with propellers at the end, or sometimes being activated automatically depending on the player's actions, such as when there are several inactivated rails in a row, and activating one activates all of them. Agent 4/Agent 8 can hop from a rail to another or a platform by pressing to jump while tilting the  towards the direction wanted in humanoid or squid form. Jumping like this can be used to perform tricks in reference to real-world grind rails that are used to perform skateboard tricks by jumping. When using the ride-rails, it is also possible to fall off if the player does not time jumps correctly and misses the place intended to land. Agent 4/Agent 8 can get on a ride rail by jumping on it while it's activated, or by dodge-rolling into it with the Dualies by pressing. They can also activate the rail that way.
