RoadRail after market Rail Gear parts are re-invented to improve performance and reduce cost. Some rail gear parts are trouble free and some parts just seem to break or wear out to quickly. Most of our after market rail gear parts are the result of customers coming to us for a solution that the original equipment manufacturer (OEM) has not solved or don’t want to solve. As an example take insulated rail wheels, typically the OEM uses a two piece rail wheel with fiber insulators. The fiber insulators cannot take the load long term so the fail. RoadRail uses a one piece rail wheel with an insulated bearing cup that is designed to carry the load long term with less parts.
