TIE PLUGGING MACHINE AND METHOD

摘要

A railroad tie maintenance vehicle is configured to seal spike holes in a railroad tie formed by the removal of railroad spikes. The vehicle includes a chassis with an integrated operator work station. The vehicle may move along railroad tracks with a plurality of wheels that support the chassis and that are configured to engage at least one railroad track. A motive power source, supported on the chassis, may be controlled by an operator within the operator work station to propel the vehicle along the railroad tracks. At least one storage vessel on the chassis contains a chemical solution used to fill the spike holes. At least two injection devices on the chassis are remotely controlled by the single operator, possibly by the operation of a single controller such as a joystick, to move into alignment with respective spike holes and to fill the spike holes with the chemical solution.
