Most westbound Pennsy trains use a connector in the southwest quadrant. Tolleston is on Gary's west side at Grant Street and 10th Avenue. However, the Pennsy is a little-used secondary line and the Wabash is now just a short industrial branch into Gary. Traffic is sparse, and like Clarke access is almost impossible. Just west of here, the Porter Branch joins the IHB track and becomes the Harbor's main line to Dolton and Blue Island Yard.
Access is difficult, traffic is relatively light and the nearby neighborhood is unsafe.
This is still a relatively busy place with about 40 trains a day. But it is difficult to access and there are much better places to view both lines. West of Highland is the twin suburb of Munster. Here, just west of Calumet Avenue is a triangle of junctions that must have been a fascinating place back in the old days. Traffic through here was heavy, and close coordination among tower operators was needed.
