Conservation and restoration of rail vehicles

They are often operated in present-day service as moving examples of living history, as opposed to static exhibits.

The restoration of historic railway equipment has gained importance in the United States, primarily because of a large amount of steam locomotives and cabooses donated by railroads to cities and museums, many of which have been displayed in parks for many years.

Examples of major projects accomplished by clubs are D&RGW 315, which was displayed in the city park in Durango, Colorado, until removed by the Durango Railway Historical Society and restored to operation,[1] as well as D&RGW 223, which was displayed at Liberty Park in Salt Lake City, Utah, until moved to Ogden and restored by the Golden Spike Chapter of the Railway & Locomotive Historical Society.

She was restored and is still privately owned, operating occasionally on the Durango & Silverton and Cumbres & Toltec Scenic Railroads in Colorado.

In parts of the United States, internally powered buses made to resemble a streetcar are often referred to as "trolleys".
