Truro yard maintained them from new, and kept on top of them.
They knew all their foibles, etc, and were excellent at keeping them going.
Truro engineers did a brilliant job.
In the last few years of First, maintenance was transferred to Summercourt, with Truro only dealing with breakdowns and emergency repairs.
Invariably Summercourt sent them back in the same condition they arrived unfortunately.
Truro and the unions objected, but finances were so tight, the response was always 'tough'.
Such a shame.
