This book is the first of two volumes on the product history of Rovex. Tri-ang was the model railway arm of Lines Bros and was the first to market a relatively cheap, mass-produced 2-rail system, with the use of plastic giving them a great edge over their principal rivals. Tri-ang Railways had a far greater range than any other British make and were one of the few manufacturers to produce special models for the export market, particularly Australia and to a lesser extent the USA. In recent years these plastic trains have entered the world of collectibles. This extensively revised edition of the book ensures that virtually every item, from the first simple train sets made by Rovex for Marks & Spencer, right through to the last products bearing the sole Tri-ang name, is illustrated and described in detail. A full check-list of all models is included with the book. This edition also includes 32 additional pages and over 100 new illustrated items uncovered by the author, Pat Hammond, in his determination to provide the definitive guide to the Tri-ang story.
