All of my train projects for my LEGO City

I have three different train projects : a metro train (first image), two trams (second image), and an airport inter-terminal train (third image). With exceptions of the two first pictures, Im planning to use 9v tracks that I'll use for every other trains, like my inter-terminal train. What do you think ? Do I need to modify something ? Do you have any ideas for a layout ? submitted by /u/Obvious-Pride-1979 [link] [comments]
