Rail gear assembly

A method of controlling a rail gear assembly, comprising:

• lowering a first wheel arm from a retracted position to an extended position, the first wheel arm having a first end pivotally coupled to a base at a first arm connection and a second end rotatably connected to a first wheel by a first axle,
• wherein a first wheel arm actuator having a first end coupled to the base and a second end coupled to the first wheel arm lowers the first wheel arm from the retracted position to the extended position;
• lowering a second wheel arm from a retracted position to an extended position, the second wheel arm having 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 being independent of the first axle,
• wherein a second wheel arm actuator having a first end coupled to the base and a second end coupled to the second wheel arm lowers the second wheel arm from the retracted position to the extended position, and
• wherein the first wheel arm and the second wheel arm move from their respective retracted positions to their respective extended positions simultaneously;
• and
• allowing 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.
