Is this WWII era spur narrow gauge?

Hello everyone,

I am trying to determine the gauge of the railway in these pictures below. I have limited information on the spur itself, except that it was constructed pre-war in Poland to reach a gravel quarry.

This photograph was taken in 1944 and is the best picture of the railway which is available:




This second picture of the railway was taken circa 1962, after the spur was dismantled. The rails in this image were preserved by the road construction, and the path forward eventually leads to the location where the first image was taken in 1944:



I have been told that this is a standard gauge railway, but after trying to compare these images to other images of standard gauge railways, I believe that this looks more like a meter gauge spur. However, my knowledge of narrow gauge railways is very limited and I am wondering if others with a more trained eye can offer any insight.

Is this spur a standard gauge, meter gauge, or some other gauge?

Thank you for your help and input.
