I thought Colin had posted here quite often, but I could find only four posts under the name of "Guest,Bo Foaks." He was registered as "Bo Foaks," but never posted under that name. He certainly seemed to have been revered.

I've wondered about that "Bo-Bo" term for the wheel configuration of diesel and electric locomotives, and Rusty Dobro's post above finally made me look it up. Wikipedia has a very comprehensive article on the UIC classification of locomotive axle arrangements. A B-B (Bo-Bo) configuration has eight wheels on four powered axles, arranged in tow 2-axle Bogies, or wheel trucks. Co-Co locomotives have two trucks with three powered axles each. I think it's mostly Co-Co Union Pacific locomotives that go past my house every hour or so, on their way across the Sierra with their mile-long trains. There are even some Bo-Bo-Bo-Bo locomotives with four 2-axle trucks, like the GE Dash 9 Series, now surpassed the current GE Evolution Series, which have a Co-Co configuration. This list of largest locomotives even has 12-axle BoBoBo-BoBoBo and CoCo-CoCo-CoCo-CoCo locomotives. Bo Foaks would have been in his glory to see them.

Rest in peace, Bo.
