Other Articulated Locomotives in the USA

The first Mallet in the USA was an 0-6-6-0 built by ALCO in 1904 for the Baltimore & Ohio railroad. It was numbered 2400 and named "Old Maud". The lack of a leading or trailing truck meant that it was only suitable for pusher service. However, it lasted for 34 years until it was scrapped in 1938.

Some of the last locomotives built in the USA were also Mallets. These were the 2-6-6-2s built by Baldwin for the C&O.

Between these two times, railroads experimented with many articulated wheel arrangements. Some, like the triplex or the 2-6-8-0s used on the Great Northern were quite exotic. Others, like the Big Boy, became some of the most famous locomotives in the world.
