MX: The Diamond in the Middle of Lake Monona.
MX is just a shadow of what it once was. Back in the day, this was a high traffic interlocking between the Chicago & Northwestern and the Milwaukee Road. Both railroads had a causeway that led to this junction. Traffic movement was controlled by signals and the Monona Tower Operator. This decrepit box is about the only remnants of the signal system. Present day, the diamond is within yard limits and only sees a few trains a week. WAMX 4187, 4223, and 4191 are pictured leading 50 grain loads over the former Milwaukee Road trackage that connects the present day Prairie Sub with the Madison Sub. Movement over the former MILW at MX is not all that common. It is typically only done when WSOR runs unit grain trains that bypass their yard in Madison.
