And now for something completely different.

 As if 3mm and 00 are not enough- I already have two 3mm layouts and am building another 3mm layout plus two 00 gauge offerings.
So I have always had a hankering for 009 and succumbed and bought a Roco 0-6-0 steam tank engine. This was followed closely by a 4 wheel carriage and wagon.
Looking on a well known auction site saw a couple more loco bodies arrive which have been motorised with Kato N gauge 4wheel tram chassis-shown in the lower photo.
The layout is 4ft long by 14 inches wide, 9mm ply framed by 2x1 planed timber. Seen with the track laid and track colour applied.
The track plan is pinched from Drury Lane and named Hillbrow.
