So Transport Direct closed in 2014 and now I am trying to find my way from Heathrow to Bristol at 19:30 or so on a (not so) bright November Monday.
Searching GWR gives me results that go to Reading bus station despite their own parent company running a bus to Reading rail station adding a 13 minute walk:
Google Maps (and traveline) shows a Megabus at 7:40PM which simply doesn't exist according to Megabus (it's not that there is no space left on the date I am checking, they run roughly every two hours and there's one at 7PM surely there isn't one at 7:40PM). And I checked the map and Cabot Circus is indeed the mall next to the Megabus stop so it's the same route.
Is there a reliable, working transit planner these days?
