Unfortunately, the Best Friend's boiler exploded after just a few months of service. Some parts of the Best Friend were used to construct another locomotive known as the Phoenix.
A replica was built in 1928 to commemorate this rather famous locomotive. This replica is now currently preserved at Norfolk Southern's headquarters in Atlanta, Georgia.
- The 1928 replica was also featured at the 1939 New York World's Fair with B&O's William Mason.
- The funnel is located behind the engineer with the whistle and valve gear.
- In 2005, it was displayed at the New York Stock Exchange (NYSE) to commemorate the anniversary of the United States' development of railroad transportation.
- There are 2 replicas that exist: the first (and more famous) replica was built in 1928 to commemorate the centenary of the South Carolina Canal and Rail Road and was widely exhibited in the following years; it is currently on display at the Norfolk Southern's headquarters in Atlanta, Georgia, and is fully functional. A second full-size replica built in 1970 is on display at the South Carolina State Museum in Columbia, SC.
- The Best Friend was the first engine built entirely in the United States – at West Point Foundry in New York – and it was the first to carry the U.S. mail.
- It is widely acclaimed as the first locomotive to be built entirely within the United States for revenue service.
