Which stations are these? The ones I regularly use still have them but looking now at Euston the columns are blank.
The platform number indicates that the feed is provided by the CIS at those stations which is often why you have a train which just has "no report" most of the way and then suddenly starts giving estimated times.
Wht do you mean departure boards? Reading used to have a row of NSE style monitors until they replaced them with some flat screen ones. I miss the traditional NSE ones!
