Blue Funnel, Merchant Navy Class locomotive, Southern 21C13 (Wrenn Railways W2278)
The loco is shown in its wartime black livery. British locomotives were painted matt black during World War Two, partly as an economy measure, and partly to prevent them being shiny, brightly-coloured targets for bombers. If a bomber was trying to target a railway station or goodsyard as a strategic piece of infrastructure, it would be easier to pick out a large gleaming brightly-coloured loco than one in matt black, especially at night.
The locomotive is displayed on top of its Wrenn Railways box. Although Wrenn were founded in 1950, the specific "Wrenn Railways" name started being used in or after 1972, after the company detached itself from Lines Brothers, which had gone bust in 1971.
