Bob has been in the Railroad Industry since 1984 where he helped start the Railroad Division for Road Machinery & Supplies in Bloomington, MN. Then in 1990, he and his good friend and business partner Roy Nelson, invented a Truck Mounted, Hyrail Track Lubricator for the railroads. The Burlington Northern purchased the first Robolube Track Lubricator that was assembled in Roy Nelson’s garage in Lakeville, MN. Since then, Robolube has grown to become the Hyrail Lubricator of choice and Robolube was relocated to their present location in 1993 after Roy’s garage became too small for operations.

Bob and Roy were always striving to improve and add to their product line while enjoying their close friendship. With Roy’s unexpected passing in 2015, Bob had to continue RBL, Inc. without his comrade Roy Nelson. RBL is here today because Bob and Roy’s Dream can never fade.

Robbie Pieper is a native of Minnetonka Minnesota.

This Company and all of us at RBL are dedicated to remembering two individuals that made our company and its successes possible.  Roy Nelson and Ryan Pieper were an integral part of RBL and their laughter, personal qualities and commitment to our success are greatly missed.   To have lost them both so unexpectedly and suddenly has left a void in RBL that can never be filled.  Their presence was an irreplaceable asset to our company and made us who we were then and who we still are today.

Roy Nelson was my dear personal friend and business partner for over 30 years, and I could not have had a better friend and partner in creating RBL, Inc.  Roy was an avid golfer, inventor and creative man.  He was such an inspiration to many, and I cannot recall anyone not enjoying the time they spent with Roy.

Ryan Pieper was my son.  Ryan loved the Railroad Industry and the people that he worked with and was so excited to be part of this great industry.  Ryan was also an avid outdoorsman and was a true sportsman and conservationist.

I was blessed to have been allowed the pleasure of working alongside my son on a day-to-day basis and I am heartbroken for the loss of such a unique and wonderful privilege.  I am proud to call Ryan my son and I will forever miss his inspiration, personality, enthusiasm and dedication to our efforts.

RBL, Inc./Robolube will never be the same without Roy and Ryan, but we promise to always dedicate our efforts and future successes to their memory and the inspiration that they gave to us.
