Some more pics from my layout.

I hand painted the LMS N2 tank myself, using flat brush and thinned Humbrol enamel, mixed to get right shade! Transfers courtesy of Dennis Williams.

The GWR pannier was a scrap JVM body on a shortened r1 chassis. Brass Cab side Number plates by Geoff Burton of Kings Cross plates.
Amazing the expertise people have which helps guys like me!
Yes,i converted a Barnstable years ago.The thing to watch is to rotate the ringfield magnet 180 degrees so that theloco runs in the same direction as the3 rail model.
A very nice langurs tank. I have a Gaiety bodied one that I would like converting to 3 rail.
