10. LNER Class A3 4472 Flying Scotsman - 100mph
The slowest steam locomotive on this list is arguably the world's most famous. In November 1934, it became the very first train of its kind to be officially verified as capable of reaching 100mph. It covered more than 2 million miles before it was retired from regular service in 1963.
9. GWR 3700 Class 3440 City of Truro - 102mph
The City of Truro was timed at 100mph no less than 30 years before the aforementioned Flying Scotsman, albeit unofficially. Built in 1903, the locomotive was taken out of service in 1931.
8. Milwaukee Road class F6 #6402 - 104mph
Number 6402 was one of 14 Milwaukee Road Class F6 steam locomotives built between January and March 1930. It set its speed record during a test run to determine the feasibility of a high speed service between Chicago and Milwaukee. All of these locomotives were scrapped.
7. LNER Class A3 2750 Papyrus - 105mph
The A3 class of LNER steam locomotive actually evolved from the same manufacturer's A1 class. Over 50 of them were built between 1922 and 1935. Papyrus hit its top speed hauling 243 tons of cargo behind it, which is an incredible feat. One of the surviving examples of the A3 class locomotives is pictured.
6. LNER Class A4 2509 Silver Link - 112mph
The is the first of two LNER Class A4 locomotives to be found on this list. Silver Link was actually the very first Class A4 locomotive to be built. It reached 112mph on its very first run, breaking all previous speed records. It was in service until 1963 and scrapped in 1965. A surviving Class A4 locomotive called Bittern, which is pictured, was once painted in the Silver Link's original silver and grey color scheme.
5. Milwaukee Road class A #2 - 113mph
The Class A was the very first steam locomotive built to operate regularly at over 100mph. Only four of them were built, and the number two train registered its 113mph top speed over a 12.5-mile run, which was completed in 1935. Sadly there are no trains of this type left in existence - all were scrapped after 1951.
4. DR 18 201 - 113mph
This train is the fastest operational steam locomotive in the world. It first appeared in the early 1970s, and is essentially the sum of a combination of various parts from old German locomotives. It managed a 113mph top speed during a trial run in 1972.
3. Pennsylvania Railroad E7 7002 - 115mph
The train pictured is the only survivor of its class, and resides in the Railroad Museum of Pennsylvania. It is a replica of the record-setting 7002 train, which managed a claimed 115mph in 1905. The train was scrapped in 1935.
2. Borsig DRG Series 05 002 - 125mph
The second of only three steam locomotives of this kind ever built set the world speed record in 1936. It did so while hauling 217 tons behind it traveling between the German cities of Berlin and Hamburg. The train pictured here is train 001; 002 and 003 were scrapped in 1960.
