Database

Train Graph Generator

I've been "playing" with the automatic generation of train graphs (a.k.a string charts) using PHP and information from the April 25, 1954 time tables in an SQL database. Currently only regular trains for the Allandale and Belleville Divisions are available. This is very much a work in progress!

2. Trains traveling over midnight. [2008-12-13]
