I wrote an e-book on: The Unauthorised History of ASTER.
A book with text and pictures on
LOCOMOTIVES THAT CHANGED THE LIVE STEAM SCENE.
This book is a “history of ASTER” from 1975 until 2016. It is a history based on the products of ASTER and not of the company. It could also be called a personal history since it is made by me and not discussed with the ASTER company or any previous or current ASTER distributor, re-seller or customer.
It can be read or down loaded for free from my website http://sncf231e.nl/
