The disruption map at the top of this page provides a quick look at where there are problems with
GWR▸ trains right across the South West and South Wales - a graphic form of Journey Check, and there's a link to Journey Check just below it.
Initially as an experiment ... I have added
Step 1 - click on the disruption map and you get a larger map showing all the network stations in th area
Step 2 - click on an individual station and you get a report from that station
Step 3 - select an individual trains to see how it's doing.
All from industry feeds / taking the best available for any particular station.
Let me know if this is any use and ideas. I did have a possible idea of zooming the map that comes up at stage one, centering it based on where you click on the initial map, and adding in full station names. Time constratints mean that would be an exercise for some time in the future though.
