摘要： The present disclosure provides for an automated spray system (100) to produce an elastomeric pad on a railroad tie. The automated spray system (100) includes a two-component spray system (102) for spraying a two-component reaction mixture to produce the elastomeric pad on the railroad tie. The automated spray system further includes a gantry system (140) having girder (146) that supports the spray applicator.
