It's exactly the same.while I don't know if it is the same as what you mentioned, in the summer of 1994, I lived in Lviv, Ukraine as part of a Rotary exchange...we flew in through Warsaw and took a train to Lviv...when we hit the Polish/Ukranian border they jacked up each railway car and rolled out the wheels for the gague of track in Poland and from other direction rolled in the wheels for the gauge of the track in Ukraine
Fantastic post!
