With only a few Freightliner Class 66s in the Powerhaul livery, pictures of two working together are at a premium. Here a pair of former DRS 66/4s pass Didcot North Junction on 25 April 2017 with the 4O18 03:07 Lawley Street to Southampton Maritime freightliner. As this was running 82 minutes late, I assume that 66420 was rescuing the failed 66416.
