black genset in scrapyard

A primary selling point At the time, gensets seemed like a good idea.

Q: I am wondering why they mark a little F on the front of a diesel. I know it stands for “Front.” However, isn’t it obvious in most cases where the front is? And in the case of a center cab switcher, where it isn’t at all obvious, why does it matter? What is the practical purpose of […]
