between points;
Big Finding enGine - osm xml to postgres parser and geohash/reverse geocoding 
Export existing bus stops and timing points (maybe call bus stations for 
icon?) as OSM XML
Export required from-to-route tuples to a database table, hopefully 
reducing for 31X routes
open export, insert billions of stops and save as osm
run parser to generate geohashes and stop names, send to database
open as osm again and enter billions of between stops lists into database by hand

adjust gtfs generator to use and generate inbetween times

generally;
check intersection parser for timing points again. (gtfs validator 
probably found them all anyway)
