These two postcards were the property of Driver Clements who wrote on the reverse the salient details of the test. I was given these by his descendants.

The two pictures, scans of a pair of torn, battered and browning images, show (1) the front of the engine, (2) the  other shows the leading offside axle box. Picture 1 was taken to show where the men watching the axle box therometers was stiting. Each on a low, wooden seat with sacking for cushioning, one over each buffer.  Picture 2 shows one of these men, in position, his back to direction of travel, wearing a heavy overcoat with the collar turned up. Both men sat there at speeds up to 102 mph. There are no signs of any restraints in these pictures.
