Preservation
Tank locomotives are popular with heritage railways for a number of reasons. They are usually cheaper to purchase than a tender locomotive due to their smaller size. This is also an advantage when working out the cost of transportation to the heritage line, many of which are isolated from the national rail network.
Most heritage railways only have short lines and do not often have turntables at both ends of the line. A tank locomotive has good visibility for the driver in both directions. As the trains being hauled are usually light the tank locomotive is more fuel efficient than a large tender locomotive.
Add to this the lower cost of maintaining the engine and the lower amount of wear and tear on the track. Another fact to consider is that many tank locomotives were bought from former industrial railways rather than the national network. Due to the higher availability it would be easier to secure a suitable locomotive for a reasonable price.
