Useful / interesting railway websites

Depends what you mean by useful, I suppose, but here goes. Some sites have been mentioned here before, but here they are together:

www.realtimetrains.co.uk

http://www.realtimetrains.co.uk/maps/areas/swml/1 - is a link to the first of a series of 6 diagrammatic real time train information. There are no links to it on the main page and the levels of folders aren't accessible, but there are links to pages 2-6 on this page itself.

www.brtimes.com

www.brfares.com - see also http://data.atoc.org/member-area (previous blog post explains).

www.opentraintimes.com previously metioned here has closed down, according to Barry Doe, but was working when I tested during writing this.

trains.im (Open National Rail times, maps and stats).

Thanks to Barry Doe and Rail magazine - p48 of issue 746 - for the information.
