The underframe and ends were weathered with Railmatch enamels (402 Frame Dirt and 403 Roof Dirt), plus a little Humbrol Metal Cote (27004). In order to produce a worn appearance to the bodywork, the bodysides were rubbed in light, vertical strokes with fine 1000-grit sanding sticks. To add a careworn aspect to the roof, I sprayed it initially with a metallic silver to represent bare metal. Using photos as a guide, I covered the roof in ‘random’ patches of Humbrol Maskol. When this was dry, the roof was sprayed in Railmatch 261 Virgin Grey, which produces a more convincing appearance than pure black. Once the dark grey coat had dried, I picked off the Maskol to reveal the silver. This created the impression of a peeling Mk 1 roof. The large roof exhaust panel was weathered with a mix of Humbrol weathering powders (Iron Oxide, Rust and Dark Earth), while the rest of the roof received an overall dusting of Humbrol’s Smoke weathering powder, with the odd streak of Rust/dark Earth creating some tonal variation.
