There were significant changes to the Bus services in July 2018. The bus information on leaflets 1:2, 2, 4 and 5 is a bit out of date but AFAIK the information here is correct. We found the Arriva site confusing and the on-line planner doesn't seem to deal with the new route 19 at all well. In September Wellington Walkers are Welcome showed that the whole trail could be walked in easy stages entirely by bus from Wellington. This site http://www.telfordpublictransport.co.uk/ seems to be up to date and easy to use.
Clock Tower in Priorslee
The clock tower in Priorsleee was, for a time. only the site of the clock tower. It has now, December 2019, been rebuilt.
