        <p>Did you know that in Switzerland, trains are permitted to have up to 255 axles? That's right! But here’s the twist: they can also have 257 axles or more. So, does this mean that a train can sport exactly 256 axles? Well, not quite—this scenario is actually off-limits.</p><br />
        <p>According to a document from the Historic Railways of Switzerland (HECH), the rule is clear: trains are prohibited from having exactly 256 axles. You might wonder why this is the case. It all comes down to the system used to count the axles as trains pass along the tracks. Special detectors are strategically placed to keep track of the wheels rolling over them, which helps train operators know whether a section of track is clear or occupied.</p><br />
        <p>The challenge lies in the counting method employed in Switzerland, which uses an 8-bit binary number system. When the count hits 11111111 (which equals 256), it rolls back around to 00000000. This means that a train with exactly 256 axles would essentially vanish from the system’s count, leading to the potential for undetected trains on the tracks.</p><br />
        <p>To mitigate the risk of accidents and ensure safe operations, the Swiss railway authority has deemed 256 axles a no-go. Allowing such configurations could lead to multiple trains being authorized to occupy the same track simultaneously. Instead of revamping the entire counting system—which would be both costly and time-intensive—the decision was made to simply ban trains from having 256 axles.</p><br />
        <p>So, the next time you spot a train rolling through Switzerland, just remember: it’s all about safety and preventing any possible mishaps on the tracks!</p><br />
