This week I’ve been busy converting to DCC a RENFE 269 - N gauge loco, that I bought last Sunday at Madrid Railway Museum flea market . The first thing to do is to conduct a general maintenance. If loco works erratically at DC, it will be worse at DCC. Then, we need to clean the energy collection system from the track, check that engine works fine, clean the gears, and replace the traction tyres.

Today I shall put forward some details about the building of a concrete stop buffer with the 3d printer. These are the stop buffers as I remember at old Atocha Railway Station. We start working at computer. As I’ve said before, I use SketchUp to draw 3D models. The stop buffers are a really simple design. I’ve designed them simple, but we can complicate it with an accurate form of buffers.

When I was seven, I received my first miniature train. A Lima H0 gauge kit what my parents gave to me for Christmas. Tracks laid over my mother’s home hall. When I was 10 I had my first model over a fixed board about 3 sq meters with two concentric ovals that covered whole room. I remember pain in my arms because a whole afternoon sat on the floor cabling under board.
