Along the Union Pacific System - This pamphlet is full of historical background to the various places the train stops, albeit a very white, conquer type history. The booklet also includes a detailed railway map of the network.
The booklet is in good condition (page 38 has some holes by silverfish), the staples are a little rusty and the cover is a little grubby. https://hungrytraveller.com.au/3d-flip-book/along-the-union-pacific-system-2/
