Inlayed track in industrial area

[Spitfire2865]

Hello, I assume this is where best to ask this.

But Im wondering, in pre 1930s, how would track be inlayed in an industrial area?

Also, how would points be inlayed. Would the blades be shorter, such as on street inlayed track, or would the inlay just avoid the blade area?

Finally, I realize wagon turntables are mostly part of inlayed trackwork, but were there any wagon turntables not connected to inlayed track?

Here's a picture of point blades on inset track on Bristol's Harbourside:

Note that all of the track has full checkrails, including around the blades, and the hand lever is also recessed flush with the road surface. However this is on a stretch of quayside; on other less critical parts of the line, there are points that appear to have been deliberately placed on non-inset spots. And, of course, I'm describing the modern situation there.
