Hey group, I was browsing through Flickr and I found this picture of a Metra F40C in Joliet on the Rock Island District. Does anyone have any idea as to why this unit was running on the Rock? I have always been under the impression that the Rock had a certain type of cab signaling back then which would have prevented the F40C's from running the line. Here is the photo, credit goes to the photographer. http://www.flickr.com/photos/31349456@N ... hotostream
Nice find. Must be some kind of special move, as you'll notice the engine is pointed inboud as well. Usually the engine is pointed outbound. Could be a pinch hit or business train (Metra occasionally runs a business train using standard equipment).
As for cab signals, I thought I heard all Metra units are equipped for RI and CNW styles of cab signal, and there's a selector switch to activate the right one. Don't take that for gospel, though, as it's a foggy recollection.
