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 reoccurring gimmick that first appeared in Sonic Heroes. 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 when they are Grinding. As soon as the playable character grind 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 mimics the Dash Panels' "Booster" design, resembling two lines of two-three rolling engines on each side of the rail that moves continuously. The more "modern" design looks like a pair of red and cyan triangles with two similar, but thinner, components connected to each of them. This gimmick hovers on each side of the rail.
