My local bus stop has had an e-ink display showing when the next few bus routes are due, since last summer. I don't get to use it that often, but when I do it's often broken or stuck displaying wrong information. Just last week it was replaced, and this morning I noticed it appeared functional, but less accurate than Google Maps and Citymapper. So much potential, but seems to be poorly implemented by Tfl.gov.uk
