The "Schlossgartenbahn" is a small 600mm narrow gauge park-railway running in the park of the castle in Karlsruhe. It was built in 1967 for the "Bundesgartenschau" and is still running during summer. From the original trains, only the "Porschelog" is active (again). But there are two other engines: one steamer and a Diesel. (More information and images can be found on this german wikipedia page) Years ago I built the railway in a rather large scale. In the meantime circuit cubes and trixbrix tracks became available and so I did it again in mini-figure scale. coupling rods are from bricks-on-rails.de Both trains are powered by a circuit cubes motor - the receiver/battery is "hidden" in the first coach. Additional weight is needed to get enough traction to move the coaches with the small LEGO wheels. They do no run a smooth as standard LEGO train wheels. I tried to hide the wheels of the coaches completely to have the same look as the original. Video of both trains - they both handle R24(!) curves. Last summer I tested the steam train on "rough terrain":

In May I showed you my version of the trains that run in the garden of Karlsruhe's palace. This was a static display. In the meantime I motorized the trains and added the automatic train control with SBricks and raspberry PI (this can be seen in the movie, when one trains stops and after a few seconds the other train starts) I also put more care into the overall layout and the children got a playground (motorized with PF). As I did not know which size I could handle I chose the minimal layout to run the two trains. For this reason the curves are almost too tight for the long and heavy trains. The feedback was very positive, so I will continue with this - next time with some more straight track elements between the curves... The layout was displayed at the LEGO Fanwelt in Cologne, the moving carousel and swing can be seen in detail at the end of the short movie: (flickr) (flickr) (flickr) (flickr) (flickr) (flickr)
