Starting with a few dabs of paint on the underframe - silver on the exhaust, a couple of spots of orange and red on some mouldings. The Hornby underframe is fairly crude so the red and orange paint don't really match up to the prototype.

After that dried I brushed over with some 'Rusty Wash' made using some Tamiya Orange Brown and a drop of Orange mixed with suitable paint thinners; and some 'Dirty Wash' made using some Tamiya Dark Grey and a dash of Orange Brown, again with suitable paint thinners.

As you can see I managed to damage the glazing mould, I have had to order a complete body spare from Peters Spares. I plan to saw the glazing so I have access to the roof to fit the DCC Decoder, wiring and lighting.

Next - Altering the internal seating to give a more prototypical look.
