The fifth edition of the fabulous Peter's Railway series.
Peter and Grandpa save the world and, in the process, make lots of money!
In their most ambitious adventure yet, our two heroes are asked if they could extend their mini railway to the village of Oaksted. It is five miles across the fields and will bring children to school, saving fuel and pollution. Of course they would love to build the new line, but how can they possibly afford to pay for it?
