Having waited almost an hour after 66758 for a different liveried 66 and wagons, cloud arrived with seconds to go so just a quick record shot looking over the estuary towards Cattawade .
66098 12.2.2018 12.36hrs 6M57 12.07 Ipswich Griffin Wharf-Watford London Concrete.
Also Top and Tailed FL66's on very nice red wagon infrastructure train Parkeston-Whitemoor passed just a few seconds before also under cloud.
I tried again for the sand at Witham and Terling Rd. but failed there too.
Obviously not meant to be this time.
