Abstract

A rail gear assembly includes a base, a first wheel arm, and a second wheel arm. The first wheel arm may have a first end pivotally coupled to the base at a first arm connection and may have a second end rotatably connected to a first wheel by a first axle. The second wheel arm may have a first end pivotally coupled to the base at a second arm connection and a second end rotatably connected to a second wheel by a second axle. The second axle may be independent of the first axle. The rail gear assembly may include actuators that move the first wheel arm and second wheel arm between retracted positions and extended positions. The actuators may permit adjustment of the first wheel arm and the second wheel arm in their respective extended positions such that a net adjustment of the first wheel arm and the second wheel arm with respect to the base is approximately zero.
