Hi Tony
Yes, I know Halewood Avenue. I presume if you spotted at Lowton you mean the transpennine route through Croft & Kenyon, can't think of any other lines that would have still existed then, apart from the WCML of course. These days I only go out to see charter trains, the current traction doesn't appeal too much - although I do like the class 57s & 60s.
I miss the days when we got classes 24, 25, 40, 47, 56, 81-7.... and on the transpennine route 45s & 46s.....
