Free books will now be on offer at St Albans station to save them from landfill.
First Capital Connect and Healthy Planet have teamed up to distribute free books from waiting rooms on Platform 2 and Platform 4.
The bookcases will be constantly restocked.
Tasha Hodge, station team leader, said: "The book exchange has gone really well. A lot of people are very interested in what we are doing and have picked up books to read on their journey. Quite a few are asking if they can bring in books, they think it’s a really good idea."
