The Secret Railway by Elisabeth Beresford

Billy is in a grump. His family have moved to an ancient, deserted sea town, with a strong pong of fish. But Grandad knows more about the old town than Billy realises. Him and his sister can have some pretty amazing adventures on a weedy railway track with its carriages that used to be posh and a street boy who's lived there all his life.

My favourite part of this book was when the boys went on one of the rickety carriages which they didn't notice didn't have any breaks! Luckily, Billy's sister (and a chicken that she found and made her pet!) saved them with a rope when they sped down hill.

Due to some boring parts where it was just chat, chat, chat, I would give this book 4/5. This is an old book but is worth hunting down second hand.
