This last week has been very busy with the wayside power team. The team decided to order two 4" linear actuators with brackets that will be attached to the current collector shoe. Designs were finalized for the third rail assembly and brought to a welding shop in San Carlos, A & D Welding, so the aluminum and steel rails could be laid out and the holes drilled in them. On Saturday the holes were drilled in the rails by Shane. Further work on the rails includes countersinging the holes for the hardware after the hardware is provided and then assembly.
Further design work was done on the shoe encloser to add rigidity. The sharp corners were filleted, and side walls were added. End tabs with holes were also added for the lid attachment.
Work in the future includes final shoe mount fitting into the shoe enclosure, shoe lid design and fitment, design of the attachment method from the shoe to linear actuator to the bogie, and third rail assembly.
