It's just past 8am on a Saturday morning at V/line's Dudley Street Sidings. Yard pilot Y129 is 50 years old and in need of a new coat of paint, but still attending to the constant task of moving passenger cars between the yard and platforms at Southern Cross Station. Looking on are a collection of N and P class locos, the latter of which are arguably even older than the Y class, being extensively rebuilt versions of the 1950's T class.
