E22 "Mallard" was used on 8 June 1948 on the London Waterloo to Exeter route. Driver Marrable took the famous A4 with a load of 481 tons tare, 505 tons full, the same that had been used on the previous trip by 35018 British India Line. "Mallard" reached Clapham Junction in 6 minutes 57 seconds and Woking in 28 minutes 47 seconds. At Hook there were adverse signals, causing "Mallard" to slow to a crawl. Even so, Salisbury was reached in 108 minutes and 28 seconds. Despite the signals earlier, the train was only 5-and-a-half minutes late. The net time was 95.5 minutes.
