IIf you travelled this morning, thank an engineer.
Engineers solve problems to make life easier.

One major problem at the start of the 20th century was inner city travel. Rails were expensive and obviously limited where a tram could go, but how could they do away with rails?
Another problem was how to move a tram without horses.
Read how the cities of Bradford and Leeds became
so unhappy with the trams-without-rails they had bought that
they actually set about building their own.
The book contains images of working models, and asks;
* Why was driving them was so difficult?
* What was the 'Diddler'

It also contains details of how you can make your own electric motor with some cheap, everyday household items.

With details of the very first British tram-without-rails and an audio version included, welcome to the fascinating history of this part of engineering.
