Crossing completely should be okay if you can get lined up at a right angle to the tracks. Carry enough momentum going in to make it over the second one.
From inside to get out could be a PITA on a 990 with its restricted steering range. Don't know how much you'll be able to get the front end turned before you hit the rail with the front tire. The theory is goose it to lift & lighten the front up a little, and go. Once the front is over the back will follow.
But I've not done yet it on my 990. Tell us how it goes!
