For a start

WELCOME
This Wiki-style site is provided by MODRATEC as a resource for railway enthusiasts and model-makers who wish to understand the art and science of rail safety engineering. The site was tentatively launched on 18 May 2009, but software issues meant that it was quickly hidden from public view. In its revised form it went on-line on 7 January 2010.

INFORMATION TREE
Information is arranged in a single tree structure. The "Welcome" Forum is the starting point. The general principle is that each "branch" of knowledge progresses from the most generic towards the most specific. Arguably, this represents a transition from the abstract to the concrete, or from the theoretical to the practical.

THE AUTHORS
As with any Wiki resource, the content here is a result of ongoing collaboration between many contributors. Anyone who feels that they can offer worthwhile material about any topic related to rail safety, or railway signals and their operation and control, is invited to apply to be considered as an author. Simply make contact with MODRATEC.

THE EDITOR
The writer of this introduction is also the editor of this resource. He's Australian, so please don't accuse him of not knowing how to spell words like authorise and colour and even signalling. If, however, you discover genuine typos or inaccuracies, please let us know. The editor is not a signalling expert, although he's not a total idiot either! However, he does claim skills of logic and structure learnt as an engineer, and is a keen student of railway practice.

YOU CAN HELP
If you do not register as a user of this resource, then that does not limit your access to it. However, as a registered user (simply click the register link on any page to request registration) you are able to post replies to any topic in order to clarify or expand the knowledge, or indeed to suggest further topics that you would like to be included. In addition, registered users may generate new topics in the General Q&A Forum.

PARALLEL RESOURCE
