This is a lot easier to do with wooden sleepers than with concrete ones. You can drive new nails into wooden sleepers almost at will, so you can keep the sleepers in place and "just" move one rail to a different position. Concrete sleepers have pre-fabricated holes for the indicated gauge, which means replacing them.
German soldiers re-gauged Soviet railways on a very short notice too when Barbarossa started.
- mmooss 1y agoBuilding a machine, if it doesn't exist, to rapidly make small holes in concrete shouldn't be hard.
- inglor_cz 1y agoIt is not just holes. I didn't want to analyze the entire problem in full, but FIY, this is how a concrete sleeper looks like: https://www.google.com/url?sa=i&url=https%3A%2F%2Fwww.dayaengineering.com%2Fconcrete-sleepers-blocks-2838240.html&psig=AOvVaw0kn8SM5UBk6C-jGbCF6o3L&ust=1747903778939000&source=images&cd=vfe&opi=89978449&ved=0CBcQjhxqFwoTCPDN_pKXtI0DFQAAAAAdAAAAABAE https://www.google.com/url?sa=i&url=https%3A%2F%2Fwww.dayaen... As you can see, the entire shape of the sleeper is adapted to the expected distance between rails. In contrast, a wooden sleeper is just a straight log with no pre-made bumps for rails.
