I am taking a trip to London soon on a Friday and will be spending some of the day between 10.00am and 17.00 pm at the footbridge at Willesden Junction. I am particulary keen to catch some freight and especially any 59 and 92 movements. Does anybody know the approximate timings of any workings involving these two classes, so that I can plan which part of the day is best to capture them. many thanks !
