Taking a break from the 3D print loco I ran some trains on my 00 gauge layout and noticed that the rake of Mark 2 BR coaches was not running quite right. Taking one off the track I found that the wheels were filthy. It was an easy job to take the wheelsets out of the bogies.
A close up shows the build up of dirt on the wheels which does not give good running on the track.
A clean with rubbing alcohol applied with a cotton bud saw the wheels returned to shiny metal and once back in the bogies a much more free running coach resulted. Just another five coaches to do!
