Hello everyone. Thank you very much for all your very interesting answers. Strange this bus accident. Even if it is not the planned route, the driver must know the height of his vehicle and know if it passes or not. Especially since it's not a few small centimeters removed. Or maybe it's his first time driving a double-decker and he's forgotten. To return to the original subject, I asked this question because I am in France and I do not know the British measurement system. And in the first photo, without a landmark, it looked small compared to the dimension on the panel. But in the photo with the SAAB it looks correct. I discovered the British railways by watching television series (Hercule Poirot, Miss Marple, Barnaby, etc) which we adore Madame and me. And I fell in love with these railways. I had already talked about it on this forum, a long time ago, but I was very ill and I remained absent all this time. Now that I'm better, I'm going to start model railroading again. I want to make a small UK-inspired network and while researching I came across the Llangollen Railway and its Berwyn station. Of course, I will not represent it 100%, but simply an evocation. Just as I do not wish to represent a particular company. Well, sorry for the novel. I will come back to you for other questions later and on another thread. Many thanks again for all your answers.
