My great, great uncle Robert F. McKee, Sr., was a design engineer at Baldwin and he would give my father different Baldwin Locomotive Works builder's cards when my father would visit him in Collingswood, New Jersey. This 0-6-0 "six-coupled Tank Locomotive" was built for the Lincoln Sand & Gravel Company, number 24. It had a tractive force of 20,200 lbs., and a combined engine and fuel car weight 122,500 lbs. This Baldwin Locomotive Works builders photo specification card is from the John R. Doughty collection.
