Heritage railways are preserved railways that operate vintage trains, often showcasing historical locomotives and carriages. They aim to educate the public about the history of rail transport and provide a nostalgic experience. Many heritage railways are run by volunteers and rely on ticket sales and donations to maintain their operations. These railways often feature scenic routes, allowing passengers to enjoy picturesque landscapes while traveling. Some well-known examples include the Narrow Gauge Railway in Wales and the Bluebell Railway in England. Heritage railways play a vital role in preserving the cultural significance of rail travel and promoting tourism.
