NS/Southern Template Car

Ive tried searching all over for the dimensions of a Template car used to haul assembled turnouts…Its pictured on page 86 of this months issue. I just recently saw one in Sandusky with a turnout on it for the first time about 2 weeks before this issue came out and would like to model it. Any chance that anyone here has scratchbuilt it? If so, A list of parts would be much appreciated!

If I remember correctly there was an article several years ago in RMC on those cars.
