Within its 168 pages, using 194 black and white (22 full-page) and 67 colour (10 full-page) views, ‘Around Cardiff by Trolleybus’ illustrates all the routes operated, the vast majority of the photographs not having been published before. The backdrop to a great many of the photographs has changed dramatically since the trolleybuses finished in 1970, and thus they present an interesting insight as to what Cardiff looked like when the trolleybuses were operating. At the beginning of each chapter, there is a small line map showing the roads the route passed along, whilst timetable frequencies are also included in each chapter. There are a number of interesting ‘now and then’ comparisons between trams and trolleybuses at certain locations. The atmospheric single-deck trolleybus service, linking the city centre with the docks area is given good coverage in colour. With the introduction of trolleybuses in 1942, a PAYE system with a flat fare of 1d was inaugurated, and a brief history of this method of fare collection is also to be found in the book. Views showing overhead junctions, feeders and dewirements, colour views of the illuminated trolleybuses, depot views, fleet list and maps are all contained in this well presented hardback A4 size book.
