50008 Thunderer leaves Long Marston on 18 September 2018 with four flats, running as the 4Z68 11:38 Long Marston to Wembley. There was certainly no chance that this would leave at 11:38, as at that time Thunderer was approaching Pershore, on its way here as the 0Z68 light engine, running 95 minutes late! Consequently this is leaving Long Marston at 13:00.
