After your post, I realized that this old steam locomotive preserved on the CRB premises of Chittagong is not just an ancient engine; it is a silent witness to the beginning of our country's railway communication. Looking at the rusty parts of the buffer coupling, wheels, and body in the picture, it is clear that the engine is being damaged due to a lack of proper preservation. The issue of making a protective canopy and giving an anti-rust coating that you mentioned is very important. In my opinion, such a historical artifact should not be kept under the open sky but under specific fencing and sheds so that it is protected from moisture and rain. Along with this, if a brief information board with a description of each part is hung, visitors and students will be able to understand its history more easily. Thank you for highlighting a wonderful historical place. Best wishes to you in this contest. 😊
