Long time ago a similar arrangement existed here in newtown. The inter-urban line had to cross over the reading newtown branch on state street. The inter-urban tracks are largely still there under the street, but the rails on the newtown branch have long been replaced since the last trolly ran. I was hoping myself to find a photo or video of this operation, either the trolley crossing the branch or waiting for a train to proceed. You have better luck than i do, as both those lines are still active, the 2 here are fast asleep.
Next stop the square, journal square station next!
