I am not claiming that they could not have replaced the rails. I am claiming that this 1944 photograph of the Treblinka spur shows a metre-gauge railway that could not have been used for transportation of fully-loaded, standard gauge rolling stock. You are welcome to take the position that this picture does not depict the actual Spur, and it's been replaced. But if you are going to claim that it is standard gauge, which I've shown is false, then I'm going to repeat my request for you to find an image of a standard gauge railway that corresponds to the picture of the Treblinka spur in the road: Again- if you want to say that the railways in these pictures are not the Spur that serviced T-II, you are welcome to make that argument and it's a separate discussion. But if you are going to claim that the railway is a standard gauge, I am asking you to provide an image of a standard gauge from a similar angle so we can test your hypothesis. I have already done it, but I'll let you pick the photographs so I cannot be accused of choosing biased images. I have presented multiple images of metre and standard gauge railways from similar perspectives and every single result supports my conclusion. I have shown you that the gauges were identical. You have NOT shown otherwise. You are mixing up 2 different pictures. With different perspectives and different horizon angles. Because of the perspective. |

Vanishing point is at infinity. If you think you're going to get a width from this, you need infinite accuracy in your determination of the angle. Your method is fundamentally bogus.
You can only get relative widths within the same perspective.

 You have not shown that the gauges are identical in any way. It is possible to use 2 different pictures if the angles are similar. I have proven that this works multiple times. If you think this is a standard gauge railway, please show me an image of a standard gauge railway from a similar angle. If you cannot do that then you cannot say you've shown it's the same gauge. |

"Vanishing point is at infinity"
No it is not, it is at an identifiable location in an image. No idea what you are saying here. There is software that will even find the vanishing point for you, although what I am doing is basically the same thing. It's not a mystery where the vanishing point is in these photographs!

Here's another reference image:  Here is the Treblinka spur (blue) from a very similar angle, it corresponds to the inner rails and not the European standard gauge (Yellow):  |

There is software that will even find the vanishing point for you, although what I am doing is basically the same thing. It's not a mystery where the vanishing point is in these photographs! Only from your perspective. The parallels meet at infinity. It is only your visual resolution that places it at a finite point (where you can no longer distinguish between 2 points). If your perspective is from a different viewing angle - that maps to the 2-D representation as a difference in that perspective. You're adding the height angle to the breadth angle. You only THINK you are drawing those lines correctly - but you are instead using confirmation bias in your determination of those lines. You fundamentally need to ascertain a metric in each picture - and THEN transform the one metric into the other. As I did. The relations between things within the same perspective will hold between different perspectives. The gauge fits about 19.5 rail widths in each picture. At any vertical to the parallels (within the same 3-D perspective). |

"If your perspective is from a different viewing angle"
But the images are not taken from a significantly different viewing angle. If that is causing my result, you should be able to find at least one image of a standard gauge railway taken from a similar angle to prove me wrong. But you won't be able to do so. Any picture of a standard gauge rail from a similar angle as the Treblinka spur will show that it is wider than the Treblinka spur. I challenge you to find one photograph that goes against this, I have provided many images from similar angles that all point to the same conclusion.

This is why I am ASKING YOU to pick a photograph that you think is from a more similar angle than the images I have used. You can accuse me of bias in choosing the photographs, fine, then show me an image of a standard gauge railway from a "better" perspective in your opinion that corresponds to the Treblinka spur. I know you cannot, because they are not the same gauge.

I don't know how to overlay the pictures as you are doing. I could overlay your pictures - removing the 3rd dimension angle though and show ANY parallel lines to be equivalent with your method.
You do not have a metric in what you are doing. Vanishing point is infinity. Your widths are arbitrary - and being determined by your bias.
