A bit of weathering on 70001. Diesel stains from the fuel fillers. Dirt and grime on the bogies. Some dirt on the steps and door handles and some more on the (many) grilles. Tried some soot around the exhaust vents also, but not an easy effect to achieve (black on black???).

Tried not to overdo it, and quite happy with the results. In most photos 70001 isn't clean, but isn't filthy either.
