I remember when I first went to Birmingham properly in 2005 (I moved there 3 years later), you could see from the streets the windows of every single bus on the upper deck were etched, many of them every single window. I remember travelling on buses and smoking (Cannabis) was commonplace. People banging on the driver’s cabin, people playing music out loud and all sorts.Just wandering, what makes you afraid to use them?
I live near 55/94 (City - Ward End) routes and most of the time never seen any problems using them.
So don't think they're that bad.
Many locals I knew at the time refused to go upstairs at any time of the day. Not sure on the routes in the city now but their local route was the 2, they wouldn’t travel on it because it was primarily single deckers, and on them it was seen as there was no way to escape the troublemakers.
