Hornby OO Gauge A4 Class Pacific Locomotive
 4-6-2 & Coal Tender finished as 60022 MALLARD in BR Green livery.
I don't have a layout to test, but it ran ok when power was applied. The loco only picks up from one side of the loco and one side of the tender by design. Motor is in the tender.
Can be collected from Crewe, Cheshire.
