...and speaking of General Purpose vehicles, General Motors has it's own version, but you're not going to find these driving down your street. Through its Electro-Motive Division, GM offered a series of 4-axle, 'general purpose' or 'GP' road switcher type locomotives starting in 1949 with the GP-7 to the GP-60M which ended production in 1994. Advances in the design of 6-axle locomotives allowing them to negotiate sharp curves spelled the end of the line for high-speed, 4-axle locomotives. Hence, the GP60M was the last of the Geeps (note the difference in spelling)
Here's another fun fact. In addition to once owning train manufacturer Electro-Motive, GM also owned a household appliance company called Frigidaire. Sold it in 1978. Must have been good products, because up until about 7-8 years ago there were 3 working Frigidaire by GM window air conditioners in my house. They had to have been built before 1978.
