I've posted this because I was interested in how High Speed lines were signalled and following a tip of from a-driver I found an interesting document on signalling used on the Channel Tunnel Rail Link (CTRL). Even though I am a lay man that understands the very basics of signalling I found this very easy to understand.

The document can be found at http://www.atkinsglobal.com/~/media/Files/A/Atkins-Global/Attachments/sectors/mass-transit/library-docs/technical-papers/signalling-at-the-st-pancras-ctrl-terminal.pdf  (http://www.atkinsglobal.com/~/media/Files/A/Atkins-Global/Attachments/sectors/mass-transit/library-docs/technical-papers/signalling-at-the-st-pancras-ctrl-terminal.pdf)but what I found particularly ironic given our frustrations at the moment is the opening paragraph which I have quoted below...

Eurostar has to compete against the low cost airlines. To do that, the passenger perception should not be that of a typical train service, with late, crowded trains, frequent failures and constant excuses. For the service to succeed, we must destroy this perception. Where we as engineers can help is in the reliability of the infrastructure and in particular the signalling.

There are times when I love Google..well most of the time really!
