A recent posting chez moi combines transport and, sort of, blogging. A train named after the man who discovered the principle behind liquid crystal displays. My posting was just a little snap of his name. Here is the stuff about the man himself, a certain Professor Gray, and here is the train.
I noticed that this train itself sported LCD type displays on the outside, with information about itself. And of course there are now many LCDs inside trains, telling you what stations will be visiting, not to smoke, etc.
Best of all, I think, are the constantly updated LCDs at stations giving you at least an up-to-date guess about what will soon be arriving, when, and where it will go. I find these signs immensely reassuring. (They are even more useful at bus stops, because until bus stops had them, there was nothing to tell you when buses were arriving or where they would be going, apart from those ludicrously complicated spreadsheets prepared last November, which were impossible to unscramble.)
At present, however, the LCDs at stations only tell you where the next train is going to go. They don’t do the same for the second or third train on the way. That can be annoying, because your decision about taking the first one might be influenced by knowing where later trains will be going.
How soon before the LCDs in trains are as good and as useful as the LCD you may well be reading this on?
By the way, is that nob beyond the LCD in my picture by any chance a camera?
