Numbering Points and Sections

I've finally numbered my points and sections. This has to be done as a prelude to wiring or I'll get hopelessly lost.

I'm only numbering points which are actually being motorised at this stage. The system is left-to-right - simple.

Also, sections are numbered in a priority order - the ones being computerised and used most often are numbered lowest. 

Sensors are shown as black dots.

I'm ignoring the tram line for this diagram.
