<div>Hi Stijn and all </div>


<div><br>


</div>


<div>In my opinion, a tunnel is something that was dug, in a hill or in mountain, under a river, ...</div>


<div><br>


</div>


<div>Otherwise I would think of a viaduct.</div>


<div><br>


</div>


<div>In that regard only your case #2 is a tunnel.</div>


<div><br>


</div>


<div>Just my 2 cents...</div>


<div><br>

<div>Hi,</div>


<div><br>


</div>


<div>1. This is a bridge: no doubt.</div>


<div><a href="https://www.google.be/maps/@50.9628551,5.0810297,3a,75y,328.21h,89.12t/data=!3m6!1e1!3m4!1sXz43z9vWyUiOpCVTschIUQ!2e0!7i13312!8i6656?hl=nl" rel="nofollow" target="_blank">https://www.google.be/maps/@50.9628551,5.0810297,3a,75y,328.21h,89.12t/data=!3m6!1e1!3m4!1sXz43z9vWyUiOpCVTschIUQ!2e0!7i13312!8i6656?hl=nl</a></div>


<div><br>


</div>


<div>2. This is a tunnel: sure enough.</div>


<div><a href="https://www.google.be/maps/@50.6138142,5.5973887,3a,75y,97.64h,84.03t/data=!3m6!1e1!3m4!1sRvKwojNbhvMdSBWG3zViLw!2e0!7i13312!8i6656?hl=nl" rel="nofollow" target="_blank">https://www.google.be/maps/@50.6138142,5.5973887,3a,75y,97.64h,84.03t/data=!3m6!1e1!3m4!1sRvKwojNbhvMdSBWG3zViLw!2e0!7i13312!8i6656?hl=nl</a></div>


<div><br>


</div>


<div>3. This looks like a tunnel, no? Or is the fact that the railway is on an embankment enough reason to make it a bridge?<br>


</div>


<div><a href="https://www.google.be/maps/@50.5508531,4.7216376,3a,89.9y,51.8h,87.45t/data=!3m6!1e1!3m4!1s4GoklQWnN5bW6ugdo1grmg!2e0!7i13312!8i6656?hl=nl" rel="nofollow" target="_blank">https://www.google.be/maps/@50.5508531,4.7216376,3a,89.9y,51.8h,87.45t/data=!3m6!1e1!3m4!1s4GoklQWnN5bW6ugdo1grmg!2e0!7i13312!8i6656?hl=nl</a></div>


<div><br>


</div>


<div>4. This one looks more like a bridge:</div>


<div><a href="https://www.google.be/maps/@50.5923923,4.6668939,3a,75y,57.67h,80.29t/data=!3m6!1e1!3m4!1s4y-C9gvI9ZsUk9jcNQX4eA!2e0!7i13312!8i6656?hl=nl" rel="nofollow" target="_blank">https://www.google.be/maps/@50.5923923,4.6668939,3a,75y,57.67h,80.29t/data=!3m6!1e1!3m4!1s4y-C9gvI9ZsUk9jcNQX4eA!2e0!7i13312!8i6656?hl=nl</a></div>


<div><br>


</div>


<div>5. And this? Brunnel or tidge?<br>


</div>


<div><a href="https://www.google.be/maps/@50.5214486,4.8868137,3a,75y,27.85h,81t/data=!3m6!1e1!3m4!1sx0n9EuFTEx27S4sCQ--GPg!2e0!7i13312!8i6656?hl=nl" rel="nofollow" target="_blank">https://www.google.be/maps/@50.5214486,4.8868137,3a,75y,27.85h,81t/data=!3m6!1e1!3m4!1sx0n9EuFTEx27S4sCQ--GPg!2e0!7i13312!8i6656?hl=nl</a></div>


<div><br>


</div>


<div>6. And if it gets shorter?</div>


<div><a href="https://www.google.be/maps/@50.5317414,4.9485687,3a,75y,39.18h,91.35t/data=!3m6!1e1!3m4!1sdTd6puiPIvGKsLBzeCzB6Q!2e0!7i13312!8i6656?hl=nl" rel="nofollow" target="_blank">https://www.google.be/maps/@50.5317414,4.9485687,3a,75y,39.18h,91.35t/data=!3m6!1e1!3m4!1sdTd6puiPIvGKsLBzeCzB6Q!2e0!7i13312!8i6656?hl=nl</a></div>


<div><br>


</div>


<div>7. And this?</div>


<div><a href="https://www.google.be/maps/@50.8660892,4.3648486,3a,75y,333.02h,85.73t/data=!3m6!1e1!3m4!1swvUHgLYhl8R5IXGVJ2QWiQ!2e0!7i13312!8i6656?hl=nl" rel="nofollow" target="_blank">https://www.google.be/maps/@50.8660892,4.3648486,3a,75y,333.02h,85.73t/data=!3m6!1e1!3m4!1swvUHgLYhl8R5IXGVJ2QWiQ!2e0!7i13312!8i6656?hl=nl</a></div>


<div><br>


</div>


<div>8. A bit more complicated: not only a railway, but also the platforms on a bridge? Or above a tunnel?</div>


<div><a href="https://www.google.be/maps/@50.8101922,4.3991964,3a,75y,63.96h,87.57t/data=!3m6!1e1!3m4!1s2ioHz72P7Ju0aTcMLalGKg!2e0!7i13312!8i6656?hl=nl" rel="nofollow" target="_blank">https://www.google.be/maps/@50.8101922,4.3991964,3a,75y,63.96h,87.57t/data=!3m6!1e1!3m4!1s2ioHz72P7Ju0aTcMLalGKg!2e0!7i13312!8i6656?hl=nl</a></div>


<div><br>


</div>


<div>9. And if you turn around:</div>


<div><a href="https://www.google.be/maps/@50.8101922,4.3991964,3a,75y,258.54h,101.02t/data=!3m6!1e1!3m4!1s2ioHz72P7Ju0aTcMLalGKg!2e0!7i13312!8i6656?hl=nl" rel="nofollow" target="_blank">https://www.google.be/maps/@50.8101922,4.3991964,3a,75y,258.54h,101.02t/data=!3m6!1e1!3m4!1s2ioHz72P7Ju0aTcMLalGKg!2e0!7i13312!8i6656?hl=nl</a></div>


<div><br>


</div>


<div>I am curious about your opinion...</div>


<div>But of course, what those things are, is not really the question. How should they be mapped? That's the question.<br>


</div>
