Track Plan. Geometry Class

Ahh, the limitations and blessings of sectional track. Personally, I like it. I am able to easily try many different track configurations and reuse all my track. Sure, I can't do arbitrary or gentle curves, but this is a cubicle, and I don't have room for large radius curves anyways. The limited geometry is sometimes a blessing in disguise. If I could do anything I wanted, it would take me much, much longer to decide on a track configuration.

As I showed in my initial plan, I have a main terminus station with a freight depot and a locomotive maintenance facility.  My plans have morphed a little since then, with an additional station track and the elimination of the team track.  I eliminated the team track to save space.  The additional station track is the result of making the passenger terminal track alignment more realistic.

Marklin uses a very well defined track geometry, and as such there is a standard parallel track distance. Using the standard methods, a 3-track terminal would look like this:



Each track is separated equally.  This just doesn't look right.  In all the train stations I have been in, the tracks between platforms are always very close together. To hack the geometry, I changed it to this:
