Gauge Change of 1885 - Adjustments at Switches & Frogs

[NW Mailing List]

 Obviously points and frogs would need some adjustment, depending on which rail was shifted. I don't think any historian has ever made reference to this.

    Amongst the Old Wise Men on this List, is there a professional track person who might be able to help with a connundrum ?   
   Did the N&W's 1885 conversion from 5' gauge to the present standard gauge require any adjustments other than the shifting of one rail inwardly?  Specifically, would any  adjustment at the frogs have been required by that change?  Would the adjustments have differed with stub switches vs pointed switches?   
   I profess almost total ignorance with respect to track geometry.  Shucks, I even struggled with the concept of underbalance in curve calculations.  My greatest professional accomplish in the realm of railroading was pushing boxcars around in the darkness.
