The crew were in no way fatigued, except for the 1st Engineer who had to perform a great deal of heavy work, such as starting up the engines, etc. When he had started up one engine single handed, he was so fatigued that he collapsed and fell off the rail, but fortunately, he was caught by a piece of 5cwt wire between the rolling guys and recovered himself.
