To view depots grouped by their owners/builders click the heralds below. Where System Maps are available you can also use those links to view the maps.
The owner/builder information was obtained from the RRSHS database. In many cases multiple railroads are listed for a depot to show successor ownership. In those cases, depots may be found under multiple heralds.
There are over 800 different railroads listed in the RRSHS database, and I have one or more pictures of about 250 of those. The 80+ heralds below represent railroads for which I have the most depot photos. I will be adding heralds as they become available, and as photos are added to my collection.
