Re: Is this WWII era spur narrow gauge?

You want to align the vanishing point, not the visual gauge separation. If you align the visual gauge separation you are comparing different points of the railway at different distances from the camera. If you align the vanishing points I think you will find that this analysis works better for a meter gauge railway:



Than it does for a standard gauge railway:



One could say that this result is only due to the fact that the image of the standard gauge at Sobibor was taken lower to the ground than the image of the quarry spur at Treblinka. I do not think that is the case, though, and I have observed these exact same results from a large sample of images. I have yet to find an image of a standard gauge railway that corresponds to the quarry spur by aligning the vanishing points in this way.

If this result were simply due to a difference in image perspective, one would assume I would be able to find at least some images of standard gauge railways that fit. But I cannot, and both the photographs of standard gauge railways you provided earlier replicate this result.

I apologize for being somewhat argumentative as I accept that there appears to be consensus here that it is standard gauge. That is just contrary to the results I have seen in my own analysis and that is why I am continuing the conversation.

Here is another side-by-side with the known standard gauge on the left and the quarry spur on the right. Both of these are different railways embedded in the same road at the same location:



Even now I find it hard to see how these are supposed to be the same gauge, but I can see that appears to be the consensus of everyone who has looked at these photographs.
