Turntable size

I’m in the planning stages of adding an engine service yard to my layout, I don’t have a great deal of real estate for the yard but a turntable is a must. What are the sizes (in inches) of the Walthers 130’ turntable and their 90’ version? Also is the 90’ version large enough for a BLI Hudson?

a 90’ TT should accommodate a Hudson. If I’m measuring the wheelbase of mine right (It’s not a BLI, but it should at least be close enough in length) - it’s about 88’(ish) from the front pilot wheel to the last tender wheel.
