From the 1999 summer timetable, there was a nominal Class 442 diagram on Saturdays that was regularly worked by Mk 1 units. I don't recall the full diagram but it certainly included the 09.00 Waterloo to Wareham and return, and the 14.30 Waterloo to Weymouth and return, and it wasn't always worked by Greyhound units. One Saturday in June 2000, it was operated by 4-CEP units 1537 and 1507. They certainly had their work cut out, especially on the Woking to Winchester leg which was scheduled just 31 minutes for 42 miles. We were actually two minutes down on arrival at Winchester, but had made this up by Southampton Central - not a bad performance for stock around 40 years old.
