Everything we know about Trainspotting 2 so far

Just in case you hadn't noticed, Trainspotting isn't about those folk who go out and record the numbers of trains they spot. Those that have seen the original Danny Boyle flick will know that trains appear more than once, though, from the wallpaper in Renton's bedroom at his parents' to one passing when Renton, Sick Boy, Tommy and Spud are standing on the platform of Corrour railway station. One wooshes past early on in T2, as Ewan McGregor makes his way back to Sick Boy after 20 years, and that bedroom wallpaper is still firmly pasted down. Where is that pub Sick Boy works at, BTW!? Looks like he didn't wanna be found.
