37670 is stored with engine troubles along with 37425 (Crewe EMD I believe) 37410 is 'dumped' at Marcroft works in Stoke after seeing use as a carriage heater or something???? 37426 was withdrawn from recent sales tender and rumours are that DB will return it to use. However as they seem quite happy to hire in 'fit' loco's from DRS, I wouldn't pin your hopes of seeing any DBS loco's back anytime soon. As DBS have proved with the class 60's, they are quite happy to dump them in storage as & when something goes wrong.
