56303 passes Holts Farm, Charlton-on-Otmoor, with the 6Z91 10:53 Calvert to Didcot Power Station flyash empties on 7 May 2013. This location had become very overgrown, with the view being virtually blocked by lineside bushes. However, in preparation for the Oxford to Bletchley line's upgrading, drastic lineside vegetation clearance has taken place, although the view is still not quite as open and rural as it was in the 1990s.
