At Control Point 147 on CSX's Berkshire Subdivision, the eastward absolute signal displays a Medium Clear aspect for a crossover move from Track 2 to Track 1. Off to the side, a 'Block Clear' indication—typically shown as a lunar white lamp—is illuminated. In accordance with CSX Signal Rule CR-1280, trains operating without operative cab signals must proceed on fixed signal indications at speeds not exceeding 79 MPH, approaching the next home signal prepared to stop.
