66121 and 66136 stand in Wembley yard at the head

of a ballast train. There were none scheduled to leave or arrive on RTT so I could not identify what the working was. 66136 still looks very smart in its DB bright red livery complete with 'Yiwu-London Train' vinyls. The loco. was repainted and had the vinyls applied in January 2017 to commemorate the first 12 000 mile Freightliner service from Yiwu in China to Barking in London.
