Railworks Track Size

Hello.
I'm trying to find out if anyone might know the answer to this question.
I'm building a wheel stop track object for a friend of mine. And trying to figure out what's Railworks track width, like from directly on one rail to the next.
Here's a picture of what I'm building that looks simular to this and knowing this piece of information ahead of time would help a lot.
And p.S, do you know what size it would be in 3D Crafter Pro.
Sincerely jpetersjr
