Tractive forces are transmitted by a drag pivot pin. [ 1 ] The bogies incorporate CAF's BRAVA ( Bogie de Rodadura de Ancho Variable Autopropulsado [ 3 ] ) system which allows gauge-changing without stopping and operating speeds of up to 275 km/h (171 mph) [ 11 ] The maximum axleload is 15.6 tonnes (15.4 long tons; 17.2 short tons).
A right-hand railroad switch with point indicator pointing to right Animated diagram of a right-hand railroad switch. Rail track A divides into two: track B (the straight track) and track C (the diverging track); note that the green line represents direction of travel only, the black lines represent fixed portions of track, and the red lines depict the moving components.
A spring pin (also called tension pin or roll pin) is a mechanical fastener that secures the position of two or more parts of a machine relative to each other. Spring pins have a body diameter which is larger than the diameter of the hole they are intended for, and a chamfer on either one or both ends to facilitate starting the pin into the hole.
At the entrance to the electrified sections a particular, high-profile contact ramp (4 + 1 ⁄ 2 in [110 mm] instead of the usual 2 + 1 ⁄ 2 in [64 mm]) raised the locomotive's contact shoe until it engaged with a ratchet on the frame. A corresponding raised ramp at the end of the electrified section released the ratchet.
Märklin's track does not have an actual third rail; instead, a series of short pins provide the current, taken up by a long "shoe" under the engine. This shoe is long enough to always be in contact with several pins. This is known as the stud contact system and has certain advantages when used on outdoor model railway systems.

The individual sprockets on a Hyperglide cassette or freewheel are designed specifically to work with their neighbours. [3] For example, the 18-tooth sprocket on a wide-range cassette (such as one for a mountain bike) will have a different ramp pattern than the 18-tooth sprocket on a narrow-range cassette, because the number of teeth on the neighbouring sprocket requires a different ramp ...
