I have fninally made a start on the 'Block Working in WA' section. Whilst far from finished, it is a beginning at least. As usual, should you wish to add your comments, memories and or suggestions about the new content, please use the many e-mail forms, or see the 'Contact' page.
Due to the nature of the topic, and how many stations it effected on this site, they are too numerous to list (okay, I lost track..!) but a good starting point is the Block Working Theory page and then the subsequent pages. More updates to come.
By the way. Today marks the sad departure from the Internet of the old SIGWA site and all of it's pages. This new site is now the only place that I will maintain - hope you continue to visit.
Cheers, and 'Line Clear' for now - Chris. J. E. French (SignallingWA).
