" On one occasion, a 9F was set to haul an express passenger train from Grantham to King's Cross. An enthusiast aboard the train timed the run and noted that twice the speed exceeded 90mph. The driver was afterwards told that he was only supposed to keep time, "not break the bloody sound barrier!" He replied that the engine had no speedometer, and that it ran so smoothly at high speeds that he just let it run as fast as felt safe."

One of the last classes of steam locos to be built and they never put speedo's on them. Who's daft idea was that?

To be honest, it wasn't that daft-the 9F's were only designed to plod along slowly with extremely heavy freight trains. They weren't designed to operate anywhere near the speed limits for express engines.
