Rosewell to Muirhouse via Polton Mill, Bonnyrigg, Eskbank, Dalkeith, Danderhall, Cameron Toll, Dalkeith Road, Surgeons' Hall, Bridges, St Andrew Square, George Street, Stockbridge, Comely Bank, Crewe Toll and Pilton. Ran from 1988-1992 in the evenings and on Sundays, every 60 minutes. For its last year of operation the Stockbridge section was withdrawn, running instead via West End and Orchard Brae, with journeys towards Rosewell serving Princes Street.
There was no Sunday evening service from what I can remember, last bus from Edinburgh on Sundays was at 1800 and from Rosewell at 1900.
