New: Peter’s Railway to the Rescue Now In Stock!! In this fourth book, the little steam railway becomes a life saver – twice. Peter & his grandpa’s miniature railway across the farm has been a lot of fun since they built it. Adventures, visits, races & near disasters have all been a part of the story so far. But now the farm is in the grip of the coldest winter for years. The tractor has frozen & the only way to feed the animals is by train. Their great project when summer arrives, is the construction of a watermill on the river to generate electricity. Apart from the appeal making something useful out of scrap, it gives Peter the opportunity to learn all about electricity, energy & power.
