I can smell the smoke from the trains on the other side of that wall ! It's a smell you never forget if you were around when steam trains were in use.
Re. Mike's point about Livery Street looking bleak, one factor might have been because the engine smoke covered everything in coal dust. Even into the 1980s when I left Brum, many buildings looked pretty grim only because they were covered in factory/industrial smoke etc. Maybe previously it was thought unnecessary to clean buildings. Today, most buildings seem to be cleaned, and you get to fully appreciate their architectural features.
