A picture is worth a thousand words!
And I worked for an electric utility. We had to replace one of the main output transformers on the 230KV side while at one of the 2500 MW stations where I worked. I believe it was the same one that received some damage during Hugo. Guess how the new transformer was brought in.
OH it was a Westinghouse unit. Westinghouse TG set and NSSS.
