The old CMG/Milw/Q xing on the Q west Batavia line was in place into the mid 70s as the J operated a local to serve Weyerhaeuser that was just west of the diamond. During these years the xing was protected both ways by stop boards,no smash boards.
In the mid to,later 70s the BN/J made a deal and the Irish Mail began serving Weyerhaeuser by going over on the J wye and the former CMG main. Later a new connection was put in the NW quadrant and the xing and the entire J Aurora branch removed.
I'm not 100% sure but I seem to recall there is a photo of the xing in the upcoming IRISH Mail article of the BRHS.
