Through doing some online research regarding this historic railroad I discovered that it has fallen on hard times, financially. In fact, there was a recent newspaper article highlighting the local sheriff's selling or auctioning off the locomotive that has been used to take sightseers of the Blue Goose Excursion along the railroad tour for the past 25-plus years. The sale was to satisfy a debt of the owners of the locomotive and railroad station property. Unfortunately, a lawsuit has been filed by another party who is also owed outstanding debts by this troubled railroad business.
There's a very nice Facebook page devoted to the Blue Goose Excursion Train that contains pictures and a history of this excursion train and can be viewed at this link.
There's also a PDF document located here which highlights the background of this historical marker and railroad.
It's sad to see a neat venture such as this excursion train fall on hard times and possibly be shut down indefinitely.
