@Peter Mugridge I did catch the 12:53 to EUS and recall the two spotters on the bench.@KT550 - were you one of the three blokes I was talking to at Harrow and Wealdstone while waiting for 730 206 + 730 236 on the 12.53 this afternoon? I recall one of them saying they were going after 701 002 afterwards...
I did notice a gent wearing a grey jacket, maybe that was you?
I recall he/you let the previous service go (like me), so I had a hunch he/you might have been waiting for 206/236.
