This is a model SD40 6-axle Diesel-Electric locomotive built by the General Motors Electro-Motive Division in 1966.  When built, it was number 1708 and was re-numbered 5008 in 2002. Over 1,200 SD40 locomotives were built between 1966 and 1972. These models were used to pull freight in North and South America along with Africa. 

Train engineers operate railroad locomotives. They are responsible for operating trains and driving them safely between stations. Most train engineers start as brake operators, switch operators or conductors, and earn promotion through experience and training.  Railroads operate 24/7, 365 days a year. Train engineers work an irregular work schedule in a cramped vibrating noisy work space. They must be totally familiar with their route, and certified for every track segment. They receive information about stops, delays, oncoming trains, and monitor gauges in the locomotive and respond correctly.  A train engineers’ job is much for complex than just blowing a horn.

Locomotive 5008 pulled many freight trains until it was donated to the Walt Disney Hometown Museum in 2017.
