Dash Eights Were Great
A pair of former Chicago and North Western GE C40-8s were heading west with a coal empty in Rochelle back in 1995. 

These cool motors were equipped with a very soulful K5H horn that sounded really cool.

A building summer thunderstorm was forming at the time and a few hours later the sky opened up with hail and a helluva lot of rain, wind and thunder.

Fun Times.
