The list of next train departures board at Gunnersbury today wasn't being particularly useful
There is another photo on Twitter taken 38 minutes earlier where the first departure was expected in 1263 minutes time, so it is possibly correctly counting down to 17:11 tomorrow - but why? About 3 minutes after I took this a westbound Overground to Richmond pulled in and a District line train to Upminster was about a minute behind it, and a good service was advertised on both routes.
