super-elevation technical questions

[NW Mailing List]

Greetings!

As I've probably bored you all before, I model the 1930's era.  I'm doing the super-elevation aspects on my mainline, using balsa strips under the outside rails and sanded down to level on the ends as the mainline straightens out.  I guess John Armstrong would be proud.  

My question has to do with sidings which parallel the mainline.   
Do they also put super elevation on them?  
Is super-elevation only done when the speeds on the  siding are above some speed like 25 mph or so?  

When a turnout is on a curve, and the siding is on the outside, It seems logical that the spur would be super-elevated as the turnout would technically need to be flat, so the spur would be at a higher level than the mainline.

Also, how far from the track centerline did they put the signals?  
I'm using a combination of semaphores(scratchbuilt) and Intermediate Block (Oregon) signals.  
How high up did they put the bottom target, or semaphore on the poles?
