Back in post #820 I said:
Saturday 30/05/87
47463 0202 Carlisle – Ayr
37423 0700 Ayr – Westerton via Shields Jn, High St Jn., Rutherglen West Jn.
The 37 was on an SRPS charter from Ayr to Mallaig. It was scheduled to call at Glasgow Central Low Level to pick up passengers, and was allowed to run early from Rutherglen, ahead of the EMU services it was supposed to follow. So we sat in Glasgow Central Low Level for about 10 minutes, gradually filling the entire station with diesel fumes, and completely stuffing the EMU services. I believe we may have set off the fire alarms, triggering an evacuation of the entire station as we departed. Rules on diesel-hauled excursions through Glasgow Central Low Level are a lot more stringent now.
I am in the process of digitising a lot of my old negatives, so here is one of 37423 at Ayr that morning, waiting for departure with the train to Mallaig. Quite a dated scene.
