Union of South Africa with the Duchy excursion

Went down to the Horsecastle farm crossing at 20 to 9. Crowded. So I went  to Yatton station.  Not so many there although by the time the train was due there were more. I wish the up platform was a long as the down one. The reason I wanted to use the farm crossing was to get her pulling away but all you can see at Yatton station is carriages rather than locomotive..
