Almost every westbound Illinois Central freight would pause in Broadview to pick up or drop off a cut of cars from the IHB interchange. That was great from my point of view because I could sit back and watch the switching to my hearts content. The Broadview yard wasn't very big, maybe 10 blocks long with 8-10 tracks. The road engines always did their own switching as required, and then reassembled their train, picked up orders, and blasted out of town. Leaving Broadview, ICRR 1639 used the spring switch to regain the mainline headed west while a track worker watched. Westbound trains worked hard upgrade from here to cross over the IHB about a mile west.
