Hi,
You have a good point about 3-way switches.
Another way to look at it is that the narrow gauges were always second class operations or too poor to upgrade the track.
I attach two photos from "On the Mainline" about the PRR.
One shows three 3-way stubs at Harve de Grace before the waterway was bridged.
The other shows Altoona with two 3-way stubs and a probably third one and a double slip stub.
Just another point of view.
The narrow gauge is like a snap shot of a period of time prior to the current standard gauges. THe RGS had many stub turnouts. Rockwood on the D&S still had a stub turnout on the tail track.
Railroads that could afford to upgrade its mainlines (PRR, NYNH&H, SP, D&RGW SG, etc) continues to upgrade the mainlines with heavier rail, spiral easements and super elevation.
Castoffs from these upgrades when to the secondary lines. How often has it been mentioned that the heavier rail on the narrow gauge was actully relay rail from Tennessee Pass or some such?
The K37's were small SG power.
Thank God the narrow gauge was treated as such and we have a view into an earlier era of railroading in general.
Food for though.
