But it's not visible when message are being displayed, like, "the next train leaves in one minute" -- exactly the time you need to know!The track number is indicated on the reader boards.
The bigger problem for me was the actions of the operator. I was literally frightened by the train suddenly moving next to me without warning. Obviously I backed away but it was quite a startle. People have been killed on platforms when running next to a moving train.
What is your take on proper signaling before departure? Heavy rail has to do it. Why not LRT?
