class 26 or 27 being transported down the motorway

[VEP3417]

was going from essex back down south/southampton with dad and saw this going down the motorway i think on the 27th of september in or around the london ish area i think, caught me off guard so after getting my phone out in a hurry i could only get a rough picture

any one know what it was and what it was doing/where it was going

Same answer as at https://www.railforums.co.uk/threads/class-26.155432/ - it was D5343 on its way between lines. It's recently moved Ecclesbourne>Great Central>Epping Ongar>Gloucestershire Warwickshire.
