Abstract
Systems and methods are disclosed for removal and replacement of container shuttles from rail tracks. An example system for a shuttle coupled to a permanent magnet may include a track comprising a first rail segment and a second rail segment. The system may include an electromagnet disposed along the track, where the permanent magnet is separated from the electromagnet by a first vertical distance when the shuttle is coupled to the track. The system may include a first ramp comprising a first angled portion and a first flat portion, and a second ramp comprising a second angled portion and a second flat portion, the ramps configured to be removably coupled to the track. A vertical distance between the permanent magnet and the electromagnet may be equal to or greater than the first vertical distance as the shuttle moves upwards along the ramps.
