Saw two double headed class 37 network rail engines,to day at 2oclock in the afternoon,pulling yellow coaches,are these the signaling test trains??:)

That's 2 of them, the four numbered 97301/2/3/4 were converted at Barrow hill and until recently at least 2 of them spent most week-ends there

interesting!! they look so smart in the bright yellow colour......:) and lots of clag too......
