An upload now from the South Wales Valley Lines. We see British Rail Regional Railways class 143 Pacers and class 150 Sprinter DMU's at work at Abercynon South and Radyr, both locations with lower quadrant semaphore signalling. At Abercynon we see the signaller exchange the single line token with the drivers and at both locations the semaphore signals at work.
