This is the same blueprint that Lee Wright used to build the incredible SD locomotive HTC trucks for his world class 7.5" gauge Electromotive diesel locomotives. Lee sold me this drawing and said; "If you ever want to build a GM SD locomotive, you will have to use this blueprint".

It has incredible details of the three-axle HTC trucks as used on the iconic locomotives of the GM SD locomotive line of the 1970's, 80's and early 90's. I believe these were first sold on the new in 1972 on the SD-40-2 and they were the trucks to have all through the SD-60's until the HTC-II arrived on the SD-70's with its steerable features, and great complexity.
