I’m still chasing 125... every time it evades me!
When I was in Glasgow late last summer I saw 33 cars - that correlates nicely with the theory there are left 36 in service (wikipedia said that last year), leaving one set on hidden away on maintenance. I did catch 125 though!
102, 104, 105, 106, 107, 108, 109, 110, 112, 113, 114, 115, 116, 117, 118, 119, 121, 123, 124, 125, 128, 129, 130, 131, 132, 133
201, 202, 203, 205, 206, 207, 208 - plus L6 outside the depot
However, according to trainlogger 101, 103, 111, 120, 126, 127 and 204 (the seven cars I didn't see) have all been active this year meaning 40 of the 41 have been active within the last nine months.
