In an earlier post I decided that consertina doors were the simplest way to I started by developing the section and then made quick decisions from there - absolutely no time to waste! The basic carriage design itself is a modified version of the Bombardier Light Rail System.
I experimented with some more programming configurations, based on the basic circulation I was trying to achieve as proposed in the tutorial last Friday. I like having the train line as the 'spine' and the programming expanding from up and above the train line.
