After completing a series of successful light test runs, the 4150 Group were happy to turn things up a notch and the crew of 4150 kindly obliged with some lively running and fine vocals from the Large Prairie. With everything heading in the right direction the Severn Valley Railway can look forward to being in the position of having another superb GWR loco to call upon !

I hope you enjoy the video.
