Just a Dapol straight from the box item with medium weathering.
This was achieved by using my usual wash and wipe method with a Humbrol matt black diluted with thinners about 50-50. The underframe was airbrushed with Railmatch Frame Dirt, Brake Dust and Matt Black. The roof was washed but not wiped – while wet I stippled with a small piece of foam to create mottled look.
