Was on a service from Bath to Westbury two nights ago and had the lovely experience of the engine ripping itself to pieces on the rear 150, the thing couldn't accelerate at all and when braking the final drive basically shook itself loose at Bradford On Avon, the guard had reported it to three driver, yet not one mention of it in the book! Why? The thing was destroying itself, think it finally gave up at Bath as the engine shut down.
