Where I can find out about models produced previously by Bachmann and Graham Farish?

A list of all Bachmann Branchline items previously produced is available here

We recommend (and provide information to) Ramsay's British Model Trains Catalogue published by Warners and edited by Pat Hammond. The 6th edition of this book is published in late 2008.

The book carries comprehensive details of all manufacturers models produced since the early 1900s to date.
