Area map, today


In the latter half of the 19th Century, the hills south of Antioch and east of Mt. Diablo hosted several coal mines served by three small railroads. Exact dating of the above map is tricky, but there are a couple of clues. First, the San Francisco and San Joaquin Valley R.R. line through Pittsburg and Antioch formally became part of the Santa Fe in 1899, Second, the Empire R.R. line is depicted as a "right of way", which indicates that the map was drawn sometime subsequent to the railroad's closing in 1897. The Empire Line was re-opened and expanded in 1900 under a different name (see below), so the map certainly dates before that time.

I love maps, and this one is one of the prizes in my collection. As far asanyone knows, this is the only one in existence. It's a pleasure sharing it, rather than auctioning it on eBay. I'd love to hear from anyone who knows something about these little railroads.
