The Trolleybus Museum at Sandtoft
The UK's premier Trolleybus Museum, being entirely devoted to this form of transport. Although it is home to a number of diesel buses, these do not generally operate on site (they do however provide a service in the form of collection of visitors from Doncaster and the Isle of Axholme tours). They also feature more at the annual Gathering Event, on the last Sunday of July when many visiting buses and cars attend the rally and many different trolleybuses provide the site service. The website is www.sandtoft.org.uk .
Here are links to a few videos of trolleybuses operating at Sandtoft (note that 619 can be seen operating on its own pages):
