The Polmadie Works pilot engine, PO1, photographed on Saturday 26th May 1979. Previously this had been Eastfield depot's 08173,
withdrawn in late 1978. As this picture shows it was initially renumbered by having tape applied over its original number, with
"PO1" simply painted above. Looking at various 1980s loco refs it seems that PO1 survived in this role until around 1984, by 1985
it was listed as awaiting disposal.
