Description
Union Pacific 4012, nicknamed "Big Boy", is a 4-8-8-4 type locomotive built by American Locomotive Company in November 1941. It is among the world's largest steam locomotives. One of 25 built, No. 4012 is one of eight of its type to survive the advent of the diesel era. Referred to as an "articulated" locomotive, because it has more than one set of drivers, Big Boy weighs 1,250,000 pounds (570,000 kg). This locomotive worked for 20 years hauling freight between Cheyenne, Wyoming and Ogden, Utah, logging over 1,000,000 miles (1,600,000 km) before its retirement in 1962. credit wikipedia
