I will do a full post later when I get a chance but used all the express between Gallaries and Sunderland in the past in 2002. My girlfriend at the time lived in Concord. I was made the mistake of getting on the 186. Only done it the once. Once done the whole 638 route! Also remember the 187/188 to Concord and the evening 638 service. Used to catch that to Prestbury Road and catch SC 20 to my house from there. Unfortunately I remember the X85 on the evening was usually a few minutes late and unfortunately means I missed THE SC 20.
