Robert "Bob" Grubba was the director of engineering for Lionel Trains in the late 1990's.
He started Broadway Limited Imports in 2001 with partners Tony Wenzel of Oriental Limited and Bob Zimet of QS Industries, maker of QSI sound systems. Broadway Limited Imports was the first company to offer sound and remote control equipped HO trains, and won the Model Railroader Magazine 2002 and 2003 Product of the Year and HO Model of the Year awards. Mr. Zimet and Mr. Wenzel sold their shares to Mr. Grubba in 2004 and the company was moved to Ormond Beach, Florida.
In 2004, Grubba founded Precision Craft Models, Inc. which was the first company to install sound systems and remote control in the smaller N scale model trains.
