After adding the brake blocks, I have been tweaking them a little to get them clear of the wheel treads and flanges when the axles are at full travel sideways. It still runs freely, but not quite as freely as before I fitted the brakes!

I gave it a coat of grey primer earlier on Saturday, and now have applied the first coats of paint, using Humbrol #67 for the initial approximation of the SECR grey (to be followed later with the proper grey after I drill the handrail holes). The roof has had a first coat of satin white (Humbrol #130), and the wheels a coat of Humbrol #133 brown, followed by a black wash on the wheels, brakes and W-irons (more or less everything below the solebars).
