I hope you like this video of 57303 hauling a 4 car Class 379 (379006) of Great Northern from Worksop Reception Sidings in Nottinghamshire to Hornsey E.M.U Depot in North London.
That's a Class 379 being towed, the first of the batch being taken to Hornsey for eventual use on Great Northern services, freeing up some Class 387s, which will go to South Eastern (in turn freeing up some Class 377s, which might be going to Southern).
