They used to be there until some point in 2011 (when the NRES website was modified perhaps??). I used to check on them fairly regularly.
They are still shown on the NRES iPhone app.
But not currently any use for checking live departures. Like you can on NRE live departure boards.You want to check your train times on here - http://www.opentraintimes.com/
Type in your location, and it can be any station, click on the icon top right from normal to advanced and it gives you the train times, reporting numbers, and if you click on the actual info.icon on a particular service it gives you a breakdown of all stations it stops at, and timings, the site also used to convey freight train times, but, that's been taken down for the time being, so, just passenger trains and bus services where applicable (Heathrow for example) at present.
Give it a whirl, it's free......

I'm working on it I've had a TRUST feed from Network Rail for about nine months, along with a TD and VSTP feed. Integrating those in to a real time system is not easy when you have a full-time job doing other things!
