Hello,
My name is Pawel and I am from Poland. I am a Z-scale modeller developing modular layout based on real Polish locations. Here you can find some photos of one of my modules in 1:220

While developing an idea to build initially technical station I ended up with module based on real station in Trzebnica. That is very interesting but compact dead end station with small engine shed and turntable at the end. The interesting part of the store is that on the other end of the station there is a bridge over the street - even part of the station passanger platform crosses this road over the bridge. Until late 60-ties there was an narrow gauge build in this road with regular service to Wroclaw. So I planned to have this small part of narrow gauge to be located under the bridge. This was 750mm narrow gauge so I decided that T gauge track is a good choice - it is a bit underscaled but 3mm agains true scale 3,4mm is acceptable for me.
Second thought was to have some not motorized rolling stock on that narrow gauge. I started to search at the Shapeways and found some designs good enough to be used on the module. I also started to search for T gauge information and end up with final decision. Try to make Z-scale narrow gauge motorized using T gauge tracks and chassis. Of course it means also supplemental narrow gauge module (modules ?) based on T gauge tracks. That is the reason why I joined this forum. I hope I will be able to show in future some progress with module on "Layout section" and to get some answers to questions which for sure be raised by me during the project.
Let's start with Z narrow gauge 3mm rolling stock work. The first one is small steam engine. I found some design on Shapeways to be a good starting point. This is French Decauville loco used on military narrow gauge railways during WWI:

I painted it and had to add chimney due to the fact that I ... broke original fragile part. This was made using small metal pipe.
