GBRf's 66.749 dragged 6E45, the 12:06 Theale to Immingham empty oil tanks, through Barrow Upon Soar on 31 May 2017. This occasional working was introduced following the closure of the Milford Haven refinery that traditionally supplied Theale. It wasn't worked by GBRf for long and is now a DB Cargo duty that runs via Banbury rather than the MML.
