The Dash Rail,[1] also known as the Grind Booster (グラインドブースター Guraindo Būsutā?),[2] is a gimmick in the Sonic the Hedgehog series. It is a variant of the Dash Panel which grants the user a boost of speed on Grind Rails.


The Dash Rail is a variant of the Dash Panel which is only found on Grind Rails. Like the Dash Panels, the Dash Rails' primary function is to send the playable character forward with a burst of speed. However, instead of increasing their user's running speed, they increase their Grinding speed. As soon as the playable character grinds into a Dash Rail, they will automatically initiate a sliding dash away from the Dash Rail at the playable character's maximum grinding speed. However, Dash Rails can only launch the playable characters in one direction.

In terms of appearance, the Dash Rails have two basic designs. The first closely mirrors the Dash Panels' "Booster" design, resembling two lines of two-three rolling engines on each side of the rail that move continuously. The more "modern" Dash Rail looks like a pair of red engine-shaped devices, with each part hovering on one side of the Grind Rails. Each of these devices have cyan lights on the rear, black light displays around the front that display cyan arrows, and two smaller engine-like components connected to them.
