Quote from: Mike K on April 30, 2024, 08:20:11 PMYears ago one iteration of the Bristol Road limited stop service (64 or 964 possibly?) used to use the tunnels inbound to St Chad's circus from Bristol Street. This was double-deck operated, before the days of the X62/X64.
For a short time the Bristol Road stopping service also did. I once rode on a Scania 32xx series on the 63 through the Queensway tunnel.
