Police managed to track down the owner of two escaped horses killed after being hit by a lorry on the A34 yesterday.
They told the owner they died near Weston-on-the-Green at about 2am.
Another five horses were herded into a field by Thames Valley Police after running loose in the village.
The A34 was shut until 7am.
And from 9.30am yesterday, sheep on the railway line delayed trains between Oxford and Banbury for four hours.
Network Rail spokeswoman Anne Marie Baston said trains were running at slower speeds. They were back to normal by 1.30pm.
