"Brake rails" sind ohne Bedeutung, das Cart bremst hier nicht. Die maximale Geschwindigkeit beträgt 8 m/s. Dies setzt eine Verhältnis von "power rails" zu "normal rails" von 1 zu 4 auf einem ebenen Streckenabschnitt voraus. Ein Streckenabschnitt ist dabei ein Reihe von Schienenblöcken ohne Richtungsänderung. Nach jeder Kurve/Knick wird die Geschwindigkeit für den nächsten Streckenabschnitt neu bestimmt, wobei hier der Schwung des Carts mit berücksichtigt wird. So kann ein Cart auch über kurze Streckenabschnitt ohne "power rails" rollen.@n@nUm das Cart zusätzlich an bestimmten Stellen abzubremsen (an Weichen oder vor einen Puffer), können Geschwindigkeitsbegrenzungszeichen an der Strecke platziert werden. Durch diese Zeichen kann die Geschwindigkeit auf 4, 2, oder 1 m/s reduziert werden. Durch das Aufhebungszeichen kann die Geschwindigkeitsbegrenzung wieder aufgehoben werden.@n@nDie Geschwindigkeitsbegrenzungszeichen müssen so neben die Strecke platziert werden, dass sie vom Cart ablesbar sind. Dies erlaubt damit unterschiedliche Geschwindigkeiten pro Fahrtrichtung.
