Transportation 'Trains and Railways' No.08: Railroad Switch builds

Below are simple text-based drawings to illustrate the possible builds and how a train runs over them.
This is the meaning of the used text-based symbols:

   [H] : straight rail 'vertical'
   [S] : Railroad Switch (straight or curved rail)
   [\] : curved rail from left to bottom or from top to right
   [/] : curved rail from right to bottom or from top to left

- Turnout line to the left continues 'to the North':
  - If not switched, then train on the main line goes straight from North to South and South to North
  - If not switched, then train on turnout line coming from the North goes to the main line to the South
  - If switched, then train on the main line coming from North stays on the main line to the South
  - If switched, then train on the main line coming from South goes to the turnout line to the North
  - If switched, then train on the turnout line coming from North goes to the main line to the South
