I have a few pdf pages of scans of blocking diagrams for farm tractors on flats.
I'm wondering if similar diagrams were made for tying down trailers on flats before the hitch was added to TOFC flats in the late 50's.
I have a few PRR F30's here I want to finish and I need to figure out how to attach a trailer. I put hitches on my later marked TTX ones, but I want the Pennsy ones to represent the earlier arrangement. I also have a few LV converted flats I want with tie downs as apposed to hitches.
I've looked at the PRR tructrain page at Keystone crossing, but its basically text describing the history, intersting, but not what I'm looking for.
