I've always found Silverburn to be the best of the shopping centres for buses getting in and out. The Fort causes tons of confusion for the buses too although I wouldn't say it's First fault as the timing boards for the first and third stops display the other stop's information so it's as if everything to Easterhouse is the first stop and not the third.Compared to issues at Silverburn the Fort is great for buses and the motorway access.
Silverburn is a nightmare with buses getting stuck at the roundabout and the confusion over what bus stops at what stand.
I feel that with Silverburn it's easier to remember where things stop once you use them once or twice.
The only thing with Silverburn is that the 3 is one of the most unreliable buses around and the 57 isn't far off and the route is so long winded too.
The key thing with Silverburn too is that the M77 has a junction that feeds into it coming from the south but it doesn't feed straight into the bus routes so it's less liable to cause an issue whereas the M8 one coming from the west feeds straight into the way the 60/60A come in and out of Glasgow Fort and considering they're horribly unreliable at the best of times it doesn't help at all.
