SystemOne undercarriage major bogie with a conventional idler and cover plateNew front and rear major bogie frames compatible only with SystemOne track are used. The new bogie frames place the shaft of the idler in the correct position for use with SystemOne track. The frames also accept bolt on lower idler guards in order to reduce material flow and packing into the track at the CTI. The bolt on lower guards cannot be used with conventional idlers. Conventional idlers are used with SystemOne major bogies in heavy packing environments in order to minimize effects of material packing on the recoil system. Conventional idlers are also used with SystemOne major bogies in order to reduce undercarriage sound emissions.Recoil Spring and Stop Tube
